Background
For this project, I've built an interactive dashboard to explore the Belly Button Biodiversity which catalogs the microbes that colonize human navels.
Test dashboard here
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.
Project was completed by using the following steps:
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.
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.
bar Chart
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.
Bubble Chart
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.
Advanced Challenge
Adapt the Gauge Chart from https://plot.ly/javascript/gauge-charts/Links to an external site. 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.
