This pie chart visualizes glucose levels for patients with diabetes, where each slice represents a patient and the slice’s size corresponds to their Glucose value. The chart includes a legend that pairs each patient’s BMI with their glucose level, and the slices are sorted by glucose in descending order. The visualization uses D3 v5 APIs including `pie`, `arc`, `scaleOrdinal`, and `schemeCategory10` to generate the SVG paths and color encoding. Data is loaded from a CSV file hosted on GitHub, and the chart is rendered within an SVG element on an HTML page.
