This example shows the diameters of the eight planets and Pluto as horizontal bars, sorted from largest to smallest, using an SVG bar chart. The chart is generated with D3 v6, employing `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the categorical y-axis, and `d3.axisLeft` and `d3.axisBottom` for the axes. Data is loaded from a CSV file and rendered as `rect` elements.
