[Vega-Lite] 3.1 HTML setup

This interactive visualization displays the historical price of the S&P 500 index over time as a dual area chart, where a smaller overview panel allows the user to brush an interval to zoom into a detailed panel above. It leverages the Vega-Lite and Vega-Embed JavaScript libraries to render the chart, with the data fetched from a remote CSV file hosted on GitHub. The visualization is implemented in a bare HTML page, using the vegaEmbed function to load a Vega-Lite specification from a separate JSON file.

Fork of [Vega-Lite] 3.3 Area Chart

This example displays a simple area chart of S&P 500 prices over time, using a temporal x-axis and quantitative y-axis. The visualization is built with Vega-Lite 5, which compiles the specification from `area.vl.json` into a Vega chart, and is rendered into the page via `vegaEmbed`. The data is loaded from a remote CSV file containing historical daily price records. The area mark fills the region below the line, showing price trends across the date range.

Fork of [Vega-Lite] 3.1 HTML setup

This example shows a simple line chart tracking the S&P 500 price over time, rendered inside a dedicated HTML container. The visualization loads a remote CSV dataset and maps the temporal date field to the x-axis and the quantitative price field to the y-axis. Built on Vega-Lite 5, the chart specification is defined in a JSON file and embedded into the page using `vegaEmbed`, which coordinates the Vega 5 runtime and rendering engine. The setup demonstrates a minimal HTML structure that combines external CDN scripts for Vega, Vega-Lite, and Vega-Embed to produce the chart.
