This visualization displays the percentage of adults diagnosed with diabetes over time, segmented by education level (less than high school, high school, and more than high school). The chart shows trends from 2000 to 2021, with shaded confidence intervals for each educational category. The D3.js code uses `csvParse` to load data from a CDC dataset and renders the raw parsed data as preformatted text. The visualization forks a template that currently displays the data in JSON format.
