{"version":"1.0","type":"rich","title":"Tracking Mouse Lesson","description":"A yellow circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. The visualization demonstrates mouse-tracking interaction built with React and D3.js, where React state manages the cursor coordinates and re-renders the circle’s `cx` and `cy` attributes. The `onMouseMove` event handler captures client coordinates within an `<svg>` element, while D3 v6 is loaded but not directly used in the logic, and React’s `useState` and `useCallback` hooks support the responsive update cycle.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e3e6f20b0965479eaa79c4cddba3c07e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
