This example visualizes temperature trends over time using a Vega-Lite line chart, with the data sourced from the Auto MPG Data Set via a GitHub Gist. The visualization is built programmatically through the Vega-Lite API, which registers Vega and Vega-Lite libraries, and employs d3.csv to fetch the dataset. The chart encodes timestamps on the x-axis and temperature values on the y-axis, with a semitransparent line style. Custom configuration adjusts axis styling, font sizes, and colors for improved readability, while the view auto-sizes to fit the browser window.
