{"version":"1.0","type":"rich","title":"task9 question2","description":"This visualization displays a heart disease dataset as an area chart, plotting age against resting blood pressure across the patient records. The chart uses D3 v7's `d3.area()` generator with linear scales for both axes, rendering an SVG path with a semi-transparent steelblue fill. The code loads data from a CSV file via `d3.csv()`, sorts records by age, and includes labeled x- and y-axes formatted with `d3.axisBottom()` and `d3.axisLeft()`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0836e2d026bb4cb9962e0bb7292dae27?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
