This interactive scatter plot visualizes the relationship between age and height for a dataset with categorical color coding. Points are colored skyblue, lightgreen, or orange based on their category, with gray as the default fallback. The visualization loads CSV data from a GitHub gist using the `csv` function, then maps values to screen coordinates with `scaleLinear` and `extent`. It renders SVG circles using `selectAll` with the `join` operator, and displays labeled axes via `axisLeft` and `axisBottom`. The plot dynamically fills the browser window with margins defined for the chart area.
