This pie chart visualizes the distribution of heart disease presence versus absence in a dataset. It shows only the proportional split between two categories, labeled “Heart Disease” and “No Heart Disease,” with the percentage of each slice displayed directly on the chart. The visualization uses the Chart.js library with its datalabels plugin to render and annotate a Canvas-based pie chart. Data is fetched from a raw CSV file on GitHub, then processed client-side by splitting rows and counting occurrences of “Yes” and “No” values. Tooltips also report percentages on hover.
