{"version":"1.0","type":"rich","title":"Make something, move and click mouse","description":"A small circle follows the mouse as it moves across an SVG canvas. Clicking the mouse drops a larger, randomly colored circle at the click position, with colors selected from a fixed palette of blue, red, yellow, green, and pink. The example uses D3.js v7 selection and event handling methods, including `svg.on('mousemove')` and `svg.on('click')`, to update circle attributes such as `cx`, `cy`, `r`, and `fill`. The SVG is sized to the full browser window.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4182c9402e3c4bf4a4e9c99f37078973?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
