Belly Button Biodiversity Web Visualisation

Overview

This project builds an interactive dashboard to explore the Belly Button Biodiversity dataset, which catalogues microbes that colonise 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.

Steps

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

• Source: 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.

3. Create a bubble chart that displays each sample.

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

5. Create a gauge chart to plot the weekly washing frequency of the individual. https://plot.ly/javascript/gauge-charts/

6. Update all the plots when a new sample is selected.
