{"version":"1.0","type":"rich","title":"fresh block","description":"A simple SVG scene displays a red circle, a rounded rectangle, and a diagonal line positioned on a fixed 960×500 canvas. The circle sits at the center-left, the rectangle occupies the upper-left area, and the line connects the circle’s center to the lower-right corner. Using D3 v4, the code selects the body element, appends an SVG container, and then creates each shape via `svg.append`, setting attributes like `cx`, `cy`, `r`, `x`, `y`, `width`, `height`, and `x1`/`y1`/`x2`/`y2` directly. No data binding or interactions occur; the visualization is purely static.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-abc9510a65b960792926c6221f8d96e6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
