This interactive bar chart visualizes the New York State Department of Corrections and Community Supervision (NYDOCCS) under-custody population, with the x and y dimensions selected via dropdown menus. The visualization includes a linked data table showing the count, percentage, and average values for each category. The D3.js v5 bar chart uses `scaleBand` and `scaleLinear` for positioning, with bar heights sorted dynamically upon selection. A tooltip displays detailed information on hover, and the data is loaded from a remote JSON source using D3's `json` function, rendered through React components.
