{"version":"1.0","type":"rich","title":"11.-Vega-Lite API 2","description":"This example visualizes San Francisco weekly temperature data as a single smooth area chart, with time on the x-axis and temperature on the y-axis. Built using the Vega-Lite API 2, the chart leverages `vl.markArea`, `vl.x().fieldT`, and `vl.y().fieldQ` to encode temporal and quantitative fields. It pulls data via `d3.csv` from a gist URL, registers Vega and Vega-Lite, and renders interactively with a tooltip handler, while custom axis and label styling improve readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/48b6fbaabbde49f7920d2478c6b342ea?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
