This scatter plot visualizes the relationship between age and BMI using an insurance dataset, with each point colored by species. The visualization uses D3 v6 with SVG rendering, loading data from a GitHub gist via `d3.csv` and parsing numeric values. Axes are generated with `axisLeft` and `axisBottom`, while `scaleLinear` maps data domains to pixel ranges. Circle marks are drawn using `selectAll` and `join`, with axis labels styled via SVG text elements in a React-friendly HTML page.
