{"version":"1.0","type":"rich","title":"Fork of Vega-Lite API Template","description":"This example visualizes annual counts of air quality records from a filtered dataset, using a scatterplot of circles where each point represents one year. It loads CSV data from a GitHub gist, filters rows by a specific indicator ID, and renders the visualization with the Vega-Lite API, registering it alongside Vega and D3 v5. The code uses `vl.markCircle`, `vl.x().fieldT('Start_Date').timeUnit('year')`, and `vl.y().count()` to aggregate values, with custom axis and label styling via a config object and a tooltip handler.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3b022cb394ae440fbab11edabb4d80c4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
