A horizontal bar chart displays the number of cancer patients for ten Indian states and union territories in 2016, using the `csv` loader from D3 v6 to fetch the dataset. The React app renders SVG bars with `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis, while custom `AxisBottom` and `AxisLeft` components generate tick marks and labels. The bar widths encode patient counts, and the chart is static with no interactivity.
