This example visualizes the Pokemon dataset as a scatter plot, mapping attack values to the x-axis and defense values to the y-axis, with each point colored by species and sized by its height and weight attributes. The code uses D3 v5’s `csv` loader to fetch data from a GitHub gist, then renders SVG circles via `scaleLinear`, `extent`, `axisLeft`, and `axisBottom`. Points are styled with fixed radius and fill colors from a custom marker function, while axis labels and a title are added using SVG text elements.
