A pie chart visualizes the distribution of Boston housing prices, categorized into low, medium, and high ranges from the BostonHousing CSV dataset. The SVG chart uses D3.js v5, with `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to generate colored slices and labels. Data is fetched via `d3.csv` and mapped from the `medv` column, with counts computed per category before rendering.
