This example shows a horizontal bar chart of planetary diameters, sorted in descending order from Jupiter to Pluto. The visualization uses D3 v6’s `scaleLinear` and `scaleBand` to map diameter values and planet names, rendering SVG rectangles bound to data from a CSV file. The chart reads the `planets.csv` dataset, converting the `Diameter` field to numbers, and displays a clean, static layout with margins and a white background.
