A React application uses D3 utilities to load CSV data on cervix uteri cancer patient counts by Indian state, rendering a horizontal bar chart with custom SVG axes. D3's `csv` fetches and parses the data, while `scaleBand` and `scaleLinear` construct the y- and x-scales, and `max` and `ticks` generate tick values. React components map over the scales and data to draw axis lines, tick labels, and colored rectangles, with SVG transforms positioning the visualization within a fixed 960×500 viewport.
