Fork of Vega-Lite API Template
This example shows a scatter plot of auto-mpg data from the UCI Machine Learning Repository, plotting miles per gallon against horsepower with points colored by origin and sized by weight. The visualization is built using the Vega-Lite API, which registers Vega and Vega-Lite libraries and renders to SVG. Data is loaded asynchronously via d3.csv, and the chart encodes tooltips for vehicle names. The code customizes axis and font styles through a config file, demonstrating programmatic chart creation with the vega-lite-api wrapper.
