{"version":"1.0","type":"rich","title":"A4 Barchart (D3)","description":"This bar chart visualizes total opioid deaths per year from 1999 to 2019, using data from the CORGIS dataset. The chart displays red bars for each year, with a hover tooltip (via SVG `title` elements) showing the exact death count. It uses D3 v7 with `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.axisBottom` and `d3.axisLeft` for axes. The SVG rendering is responsive to the window size, and the data is loaded asynchronously via `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b531b46648424c5cbdf96cd0cf9c7af8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
