{"version":"1.0","type":"rich","title":"[Vega-Lite] 3.2 Line Chart","description":"This example shows a simple line chart of the S&P 500 index over time, plotting price against date. The visualization uses a Vega-Lite specification (version 5) loaded from an external JSON file, with data sourced from a GitHub-hosted CSV (sp500.csv). The chart is rendered in an HTML page via the Vega-Embed JavaScript library, which pulls in Vega and Vega-Lite at runtime. The code defines the mark as a line and encodes the x-axis as temporal (date) and the y-axis as quantitative (price), with a fixed width of 360 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/56c09f3cf1c14b61bde137530cc99256?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
