This example plots the daily adjusted closing price of Apple stock (AAPL) as a line chart, with time on the x-axis and price on the y-axis, using a minimal dark-themed design. It loads CSV data from a GitHub gist via `d3.csv` and renders the visualization with the Vega-Lite API, specifically using `markLine` and encodings for temporal and quantitative fields. The code registers Vega, Vega-Lite, and Vega-Tooltip, customizes axis and label styles via a configuration object, and auto-fits the chart to the browser window.
