This example uses the Vega-Lite API to visualize page visits over time, plotting each visit as a small black circle with timestamps on the x-axis and page names on the y-axis. The chart is rendered as an SVG via the View API, with data loaded asynchronously from a CSV file using d3.csv. The API is registered with vega and vega-lite, and a custom config adjusts axis and label styling for readability.
