{"version":"1.0","type":"rich","title":"Loading COVID-19 Vaccine CSV Data","description":"This example demonstrates how to load and parse a CSV dataset of US state-level COVID-19 vaccination records, covering daily updates from April through September 2021. It displays the file size in kilobytes, row count, and column count. The code uses D3 v5’s `d3.csv` method to fetch and parse the data, then accesses `data.length` and `data.columns` to summarize the dataset. Alternative approaches using `fetch`, `async/await`, and `d3.csvParse` are also shown in commented-out sections.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9610ca3fb5c74b4c9884ae122cc6b892?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
