{"version":"1.0","type":"rich","title":"Vega-Lite API Template - Line/Area chart","description":"This example shows a line-area chart of weekly temperature data for San Francisco, with the area fill emphasizing the variation in temperature over time. The visualization is built using the Vega-Lite API, with `vl.markArea()` defining the mark type and `.encode()` mapping the `timestamp` field to the x-axis and `temperature` to the y-axis. Data is loaded asynchronously via `d3.csv` from a GitHub Gist, and the chart is rendered with an SVG view, configured with custom axis styles and tooltips through the `vega-tooltip` handler.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4d46510f4ae14a1e8bfaca69949a6b48?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
