Positions of tiles for US grid map visualization.

Install

npm install gridmap-layout-usa --save

or

bower install gridmap-layout-usa --save

The data files can be found in the dist directory of the installed package. Either one of these files below can be used:

• dist/gridmap-layout-usa.json
• dist/gridmap-layout-usa.csv
• dist/gridmap-layout-usa.js
• dist/gridmap-layout-usa.min.js

The data in each file is an array of tiles (provinces). Each tile is in this format:

[
  {
    "x": 2, // column index
    "y": 0, // row index
    "key": "AK"
    "name": "Alaska"
  },
  ...
]

Example usage

Please see this example for how to use this layout with D3 or you can use the ready-to-use component d3Kit-gridmap.

Development

The positions of the tiles are taken from this article by New York Times.

You can modify src/input/map.csv to change positions, then

npm run compile

Quality metrics

I have written about an evaluation method for grid map in this blog post. To run the script to evaluates different layouts:
