Belly Button Challenge

Deployment

Here is a link to the dashboard: https://imaadullah.github.io/belly-button-challenge/

Background

In this assignment, you will build an interactive dashboard to explore the Belly Button Biodiversity dataset, which catalogs the microbes that colonize human navels.

The dataset reveals that a small handful of microbial species (also called operational taxonomic units, or OTUs, in the study) were present in more than 70% of people, while the rest were relatively rare.

Instructions

Complete the following steps:

1. Use the D3 library to read in samples.json from the URL https://2u-data-curriculum-team.s3.amazonaws.com/dataviz-classroom/v1.1/14-Interactive-Web-Visualizations/02-Homework/samples.json.

2. Create a horizontal bar chart with a dropdown menu to display the top 10 OTUs found in that individual.

   • Use sample_values as the values for the bar chart.
   • Use otu_ids as the labels for the bar chart.
   • Use otu_labels as the hovertext for the chart.

3. Create a bubble chart that displays each sample.

   • Use otu_ids for the x values.
   • Use sample_values for the y values.
   • Use sample_values for the marker size.
   • Use otu_ids for the marker colors.
   • Use otu_labels for the text values.

4. Display the sample metadata, i.e., an individual's demographic information.

5. Display each key-value pair from the metadata JSON object somewhere on the page.

6. Update all the plots when a new sample is selected. Additionally, you are welcome to create any layout that you would like for your dashboard.

7. Deploy your app to a free static page hosting service, such as GitHub Pages.

Advanced Challenge Assignment

• Adapt the Gauge Chart from https://plot.ly/javascript/gauge-charts/ to plot the weekly washing frequency of the individual.
• You will need to modify the example gauge code to account for values ranging from 0 through 9.
• Update the chart whenever a new sample is selected.

File Organization and Structure

• Located in the parent directory are two folders and the index.html file.
• The Resources folder contains the samples.json file as a reference.
• The static folder contains the two javascript files app.js and bonus.js that were used to build the dashboard.
