Utilizing JavaScript, HTLM, Python, D3 library to read json files, build an interactive dashboard to explore the Belly Button Biodiversity dataset, which catalogs the microbes that colonize human navels. App is deployed to a static page hosting service, such as GitHub Pages.

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.
Complete the following steps:
-
Use the D3 library to read in
samples.json
from the URLhttps://2u-data-curriculum-team.s3.amazonaws.com/dataviz-classroom/v1.1/14-Interactive-Web-Visualizations/02-Homework/samples.json
. -
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.
- Use
-
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.
- Use
-
Display the sample metadata, i.e., an individual's demographic information.
-
Display each key-value pair from the metadata JSON object somewhere on the page.
-
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.
-
Deploy your app to a free static page hosting service, such as GitHub Pages.
- 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.
