{"version":"1.0","type":"rich","title":"SFO NOAA Summary of the Month: Average Temperature 1955-2020 with Vega-Lite API","description":"This visualization plots monthly average temperatures recorded at San Francisco International Airport (SFO) from 1955 to 2020. Each semi-transparent circle represents a single month’s average temperature on a time-series axis, with a tooltip showing the exact value. The chart uses the Vega-Lite API and its `markCircle` encoding, with `vl.x().fieldT` for the date and `vl.y().fieldQ` for the temperature. Data is loaded via D3’s `csv` function from a NOAA-hosted GitHub gist, and the rendering is handled by Vega-Lite with custom axis styling from a config file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/73233f96596344c0b285cf499f7ecb28?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
