This pie chart shows the distribution of gym types—Premium, Budget, and Standard—across ten sample gyms, including the count and percentage for each category. The visualization uses D3 v7’s `d3.pie()` and `d3.arc()` to generate the SVG paths, with a `d3.scaleOrdinal()` color scale based on `d3.schemeCategory10`. Each slice is labeled with its type, count, and percentage, computed from the hardcoded `gymData` array. The chart is rendered as an SVG, with the legend and labels placed directly on the arcs using `arc.centroid()`.
