Plot.ly Work - Belly Button Biodiversity

In this assignment, built 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.

Plotly

1. Used the D3 library to read in samples.json.

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

• Used sample_values as the values for the bar chart.

• Used otu_ids as the labels for the bar chart.

• Used otu_labels as the hovertext for the chart.

3. Created a bubble chart that displays each sample.

• Used otu_ids for the x values.

• Used sample_values for the y values.

• Used sample_values for the marker size.

• Used otu_ids for the marker colors.

• Used otu_labels for the text values.

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

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

Advanced Challenge Assignment

• Adapted the gauge chart to plot the weekly washing frequency of the individual.

• Updated the chart whenever a new sample is selected.

Deployment

Deployed app to GitHub Pages.
