{"version":"1.0","type":"rich","title":"旧金山热力图","description":"This visualization displays temperature readings in San Francisco over time as a scatterplot, with each circle representing a daily measurement plotted against date and temperature axes. The chart includes axis labels, a title, and a grid-like appearance from extended tick lines. Built with D3 v5, it uses `scaleTime`, `scaleLinear`, `csv`, and `axisBottom`/`axisLeft` to load and render the data as SVG circles with semi-transparent steelblue styling, sourced from a CSV file hosted on VizHub.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b8216716fa1f427cb07a49d5f5427cc7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
