{"version":"1.0","type":"rich","title":"Variants","description":"This visualization aggregates COVID-19 variant counts by location using a bar chart, with each bar’s length representing the number of sequences and color encoding the variant type. It loads data from the Our World in Data COVID-19 variants CSV via the `d3.csv` method. The chart is built with the Vega-Lite API, configured through `vl.markBar`, encoding fields for location, sequence count, and variant, and rendered using `vega` and `vega-lite` libraries with tooltip support from `vega-tooltip`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0708fab6e7b544f2a9ecc578c6fc205e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
