{"version":"1.0","type":"rich","title":"Vega-Lite API Temperature Area Chart","description":"This example visualizes weekly temperature data for San Francisco as a smooth area chart, with the y-axis mapping temperature values and the x-axis representing timestamps. It demonstrates the Vega-Lite API by programmatically constructing a chart specification using its method chaining, including `vl.markArea`, `vl.x().fieldT`, and `vl.y().fieldQ`. The visualization is rendered via Vega and Vega-Lite, with data loaded using d3.csv, and uses custom axis styling from a shared config plus a tooltip handler from Vega Tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ca959f04828041999b9ee0e53eebe110?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
