{"version":"1.0","type":"rich","title":"Massachusetts Daily COVIations - Interactive Barchart","description":"This interactive bar chart visualizes daily COVID-19 vaccination doses administered in Massachusetts from April to September 2021. Each bar’s height is proportional to the number of doses given that day, using a d3.scaleLinear mapping. Hovering over a bar dims the rest, and a tooltip displays the exact date and dose count. The visualization uses D3 v5's selection API and SVG rendering, pulling data from a public US vaccination dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/76d42bdc6e7d4f468c436e9585a57cb2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
