humanitiesplusdesign / palladio

An application that brings humanities research methods to data visualization.

Installation

Palladio is a supporting library and set of components. It's best-known use is in the Palladio app, which can be found at https://github.com/humanitiesplusdesign/palladio-app. In order to run Palladio locally, first make sure you have yarn installed and then use yarn to install the dependencies and build the assets:

git clone https://github.com/humanitiesplusdesign/palladio-app.git
cd palladio-app
yarn install
yarn build

Then simply run a local web server from this directory -- if you have python installed, you can just use:

python -m http.server

or on python 2.x:

python -m SimpleHTTPServer

Development

The servable files in the assets/ folder are built by webpack. Running yarn develop will set webpack to automatically detect changes in the src/ directory and update the compiled Palladio files as required. In this state, webpack will update palladio.js and palladio.css and their related assets only (not the minified versions). To create new assets suitable for distibution, use yarn build, which creates all the needed assets (minified and unminified).

palladio's Issues

Timespan scales overflow the view area in some situations

If a filter is already in place when he timespan is added, then the filter is removed, the lines will overflow the view area.

Errors if linking field happens to be the field chosen for countDescription

Timespan component - allow setting of start/end date dimensions

Currently it just uses the first 2 it finds

Errors if primary table doesn't have a unique key

Add a generated unique key if no key exists

Timeline filter cuts off last date in dataset

See data in issue #1

In graph view, "sizing according to", should be a radio selector

So that people can't unselect all.

timespan filter doesn't stay applied when loading from a save file

Use case: visualize all connections active during a time range on the basis of existence, rather than start date

This use case relates to an attempt to visualize connections between ancient Greek cities on the basis of the co-presence of specific coin types. The user therefore wants to create a time range visualization by the period of existence of each coin type (this works), and then filter that range to show which types were being minted within a given period of time. All types have start and end dates. When a time range visualization is constructed and displayed as bars, all types appear with both start and end dates. When a time-range filter is created, however, it only filters by start date (so "all types that start to be minted between 550 and 525). The user's query is "all types that either start, end, or continue to be minted during the time range 550 and 525" (and, conversely, no types that are not being minted during that time range). Is this a functionality that already exists? If not, it would be really useful, and in keeping with the purpose of Priestley's original time-range bar graph ("who is alive at point X?").

svg data layer export in Map view not working

"Document is empty"

Pre-filtering by dimension or wizard

For when a dataset is possibly too large.

Use cases:

1. Choose a time period (1800 - 1950)
2. Facet dimensions or combinations of dimensions (every letter for which Voltaire is an author or recipient - or for multiple people)
3. Network-based selection (letters relating to Voltaire or people he corresponded with)
4. Location-based

stuck on loading

The console shows this error:
Uncaught TypeError: Cannot read property 'map' of undefined

Loaded 3 tables. The application hangs on the data page. It won't move to any view page.

Google spreadsheets can no longer publish to web as format:csv

Apparently this functionality, which was necessary to load a Google spreadsheet directly into Palladio, was removed in the latest version, and is not likely to come back. According to this user forum, some people have been able to load csv from a Google spreadsheet by changing the "Share" link to /export?format=csv&id or export?format=csv, at least as of last May. But this does not work when trying to load into Palladio at the moment. If there's a fix on the Palladio side, that would be best, since the load-from-sheet function is really convenient; but if not, that tab should probably not offer the option to load from a Google spreadsheet.

I tried loading from a spreadsheet that had been published to the web with the publication link (which ends in html), with a manually edited version that ended in csv, with the normal "anyone can view" sharing link, and with the "anyone can view" sharing link changed to /export as above. All produced the same error message: "Sorry, an error occurred while fetching the data".

Alluvial diagram component

Timeline: ISO datetime format for data type

Hi Palladio team,

First of all thank you very much for your remarkable work, I'm very proud of writing the very first public issue!
When modifying a Data Type format for a column, the list of possible datatypes lacks ISO datetime format: values like 2012-03-31T15:30:57 or 2012-03-31T15:30:57.123456Z are not recognized as Date/Year, and the interface freeze.

Thanks in advance for your help.

Download is not working

It seems like the project download is not working (tested on Chrome and Safari)

Lint geoJSON in map view on import?

Could use https://github.com/mapbox/geojsonhint

Additional metadata

Add additional metadata - conversation w/ @cncoleman

• Date
• optional sub-title
• [ ]

Facet headers should not scroll

Only the cells should scroll.

Choosing an alternative aggregation results in error in sample data set

cannot load SPARQL table

While I am able to retrieve data from a SPARQL endpoint through the Palladio interface, it does not give me the option to then load the table. For example, using the British Museum endpoint http://collection.britishmuseum.org/sparql.json:

SELECT ?type (COUNT(?type) as ?n)
WHERE {
  ?object bmo:PX_object_type ?object_type .
  ?object_type skos:prefLabel ?type .

  ?object ecrm:P108i_was_produced_by ?production .
  ?production ecrm:P9_consists_of ?date_node .
  ?date_node ecrm:P4_has_time-span ?timespan .
  ?timespan ecrm:P82a_begin_of_the_begin ?date .
  FILTER(?date >= "1580-01-01"^^xsd:date && ?date <= "1600-01-01"^^xsd:date)
}
GROUP BY ?type
ORDER BY DESC(?n)

I can preview the results successfully:

However the "Load data" button remains inactive:

Bug with refining dimension after adding a link in refine view

Facet filter dimensions stack when configDimensions is pre-populated

The width is not properly calculated.

New "Try with sample data" link does not load.

BC date issue - filters on negative years don't work properly

Saving/downloading blows up links/extensions

We over-write the file ID in the links :-/

Facet filter saving

Saving filters may be broken?

Facet filter "Clear" and trash-can icon display even when showControls is false

Need to add data-ng-show="showControls === 'true'" to these elements.

Get map box +/- symbols into the build

Component re-architecture

Allow for a simple API to add Palladio components to a web page.

• timespan
• map
• facet
• table
• graph
• timeline
• gallery

BC date issue - timespan treats negative dates as positive

Drag icon in modal selector doesn't show up

Saving map should save positioning

Revisit load/save approach for filters

Need to support filters inside the filter area that can also be used as visualizations.

Allow an "ignore" option for special characters in data

When special characters are valid, we should be able to "ignore" and the red dot should change to a check mark to indicate that the issue has been checked and ignored

Facet filter dimension selection not working

I could only load one dimension.

Updating data

When a previously viewed data set is updated (a table deleted, modified offline, re-attached to primary table) is does not appear in visualization interface and no error is thrown.

Gallery view has usability issues

Doesn't really make sense to allow gallery dimensions to be chosen from more than one table.

Deleting a table (and adding another

In map view - change to "live" editing

Changes in "edit" mode in the setting panel would be more intuitive if they resulted in live changes on the map. "Save" button should turn into a "done" button.

Make table dimensions sortable directly

Facet filter should be sortable/draggable

Errors for data sets with no date dimension

Data limit?

I just loaded a primary table with 63 unique rows but in the facet filter, tabular view, and gallery view I see only 40 unique people.

Filtering on the map acts strangely with point-to-point map

Download (save Palladio json file) fails

Using 1.1.0 alpha01
Download launches another empty browser window.

Display multiple place names associated with the same coordinates

Palladio 2.0?

Palladio is becoming the data exploration and data-staging platform for digital publication. So the refine/data view more than ever needs the CSV fingerprint-style view of each attribute in a table. Currently, there is no way to know that we only have, for example, birthdates for 40% of the people in the database. So we have no means, through the interface, to evaluate a temporal view of the data. obviously, the same goes for spatial or relational data.
If 50% of Voltaire's letters are missing recipient values, we need to show that as well as the missing destinations. This is where the Fineo-type alluvial diagram can be helpful. CSV fingerprint will only show what is missing in one table. We need to see, more importantly, what is missing in relationships.

Map values with no dates

We have needed for some time to address the problem of incomplete data. One solution for this in mapping is to create a map layer of points or travels for which we have no dates. That makes it necessary to be able to add a data layer based on filters. If we can show points with no dates in red, then run a time phase for the other points, in another layer, we can at least see what we are missing and maybe, if we are lucky, a pattern.

Adding a facet dimension triggers multiple updates

This is actually an issue with the modal directive. Due to use of a label element, clicks get blocked/propagated oddly. Switching to use of a span for the description (input element is not displayed anyway).
