This example demonstrates a line chart of temperature over time, using data from the UCI Machine Learning Repository’s Auto MPG dataset via a Gist. The visualization is built with the Vega-Lite API, which registers Vega and Vega-Lite libraries, and renders as an SVG. The chart encodes time on the x-axis and temperature on the y-axis, with tooltips enabled for data inspection. D3 is used to load the CSV data, and the configuration customizes axis styling and label fonts for readability.
