{"version":"1.0","type":"rich","title":"Activity71","description":"This example shows a gradient-filled area chart of sales over time, using D3 v7. It loads data from a CSV file hosted on GitHub Gist and renders the visualization as an SVG. The code uses `d3.area` to generate the area path, `d3.scaleLinear` for both axes, and `d3.axisBottom`/`d3.axisLeft` for tick marks. A custom `linearGradient` with two color stops fills the area, and the chart includes labeled x- and y-axes. The page also imports a local ES6 module to demonstrate modular code.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2d43eeaa8f144dae90577fe549b0bc3c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
