{"version":"1.0","type":"rich","title":"[Vega-Lite] 3.4 Composition","description":"This example shows the S&P 500 index price over time as two stacked area charts, one above the other. The upper chart displays the full temporal range with a standard height, while the lower chart repeats the same data at a reduced height of 60 pixels. Both charts use the Vega-Lite specification language within a single `vconcat` composition, referencing the sp500.csv dataset. The visualization is rendered in the browser using the Vega-Embed API, which loads the vega-lite v5 schema and executes the chart definitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/512913c2a5d542579b19c85e325d525e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
