{"version":"1.0","type":"rich","title":"Practice Covid Vaccine data of Vega-Lite API Template","description":"This example visualizes Covid-19 vaccine data by manufacturer using an interactive bar chart built with the Vega-Lite API. It shows the total vaccination counts for each location, colored by vaccine type, with tooltips displaying quantitative totals. The code loads CSV data via `d3.csv`, configures axes and styling through `config.js`, and renders the chart using `vl.markBar` and `vl.encode` chaining. The visualization adapts to the window size and uses Vega-Lite’s SVG renderer with tooltip support.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/10eea256f24e42eda0d0d11c4c7ccb35?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
