This fork of a Vega-Lite API template displays a scatter plot of quantitative fields `gap` and `depth` from a CSV file fetched via d3’s `csv` function, with points colored by the categorical `place` field and a tooltip showing that same attribute. The visualization uses the Vega-Lite API (`vl.markCircle` and `vl.x().fieldQ()`) to define the mark encoding, then renders it as an SVG via Vega-Lite, with the `vega-tooltip` handler attached. The chart’s width and height are set to fill the browser window, and axis styling is customized through a config object for readability.
