This visualization displays cancer patient numbers across Indian states and union territories for the year 2016, using a bar chart rendered with SVG. The React component loads data from a CSV file via `d3.csv` and maps each state to a rectangle using `scaleBand` for the y-axis and `scaleLinear` for the x-axis. The chart is built with D3 v6 and React 17, with bars positioned starting from the left edge of the SVG canvas.
