Introduction

This project is about building 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.

Design

For this purpose, D3 library is used to read in samples.json. and then these items added to the page:

1. A dropdown menu which filters each subject ID (person) in the page.

2. A demographic information section which is designed to show the key-value pairs from the sample meta data of JSON object for each sunject ID(individual).

3. Horizontal bar chart to display the top 10 OTUs found in that individual and uses :

• sample_values as the values
• otu_ids as the labels
• otu_labels as the hovertext

4. A bubble chart which uses:

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

5. A donut chart with a needle which acts similar to a guage chart to display the weekly washing frequency of the individual.

By choosing a new sample from dropdown list, the demographic information section and all of the plots get updated.

And finally this is how the dashboard looks like:
