This example shows the daily closing price of the S&P 500 index as a simple line chart, with time on the horizontal axis and price on the vertical axis. It uses the Vega-Lite specification language, loaded via the Vega-Embed API, to parse a JSON configuration and render the chart. The data is fetched from a CSV file hosted externally, and the chart is drawn into an HTML div element using the Vega runtime library.
