This example shows an interactive scatterplot of automobile data from 1980, plotting miles per gallon against horsepower, with each point colored by origin and sized by weight. The visualization is built using the Vega-Lite API (vl) with a custom configuration that removes axis domains and enlarges label and title fonts. Since it is a fork of an API template, it loads data from a CSV file using `d3.csv`, then renders the marks with `vl.markCircle`, encoding position, color, size, and tooltip fields directly in `viz.js`. The view resizes to the window and includes a tooltip handler from Vega Tooltip.
