{"version":"1.0","type":"rich","title":"Mouse Follower Simple","description":"This example demonstrates a simple interactive visualization where a circle follows the mouse cursor across the screen. The circle is initially positioned at coordinates (50,50) and updates its position in real-time in response to mouse movements. The code uses the D3.js library (v7) to select the `#app` div, append an SVG element sized to the full window dimensions, and create a circle element with a radius of 50 pixels. The visualization listens for `mousemove` events on the SVG and uses the event's x and y coordinates to update the circle's `cx` and `cy` attributes, creating a direct and responsive tracking effect.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
