This donut chart shows the distribution of housing data by ocean proximity using a dataset from a GitHub repository. The visualization displays categorical slices of a pie, each colored by its category, with direct labels on the segments and a legend showing category names and counts. The example is built with D3 version 6, utilizing `group`, `pie`, `arc`, and `scaleOrdinal` to process CSV data and generate the chart, which is rendered as SVG. The title "Housing Distribution by Ocean Proximity" is displayed above the chart.
