{"version":"1.0","type":"rich","title":"Heart Disease Population","description":"The visualization tracks the highest-populated country of heart disease patients from 2000 to 2016, showing how the leading country changes annually. It renders an area chart with a smooth curve, using blue lines and skyblue fills, with red tick labels and violet axis labels. The code uses D3 v5 APIs including `scaleLinear`, `line`, `area`, `curveBasis`, `axisLeft`, and `axisBottom` to generate the SVG. Data comes from a CSV file loaded via `csv`, with population and year values parsed as numbers before rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2ce35bd8e1004e17a874a4913f165c1c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
