Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The example uses React's `useState` and `useCallback` hooks to manage mouse coordinates, with the `onMouseMove` event handler updating the circle's center. D3's `arc` module is imported but not used, while the SVG `<circle>` element is rendered directly through ReactDOM. The visualization demonstrates a simple interactive pattern without any data source or animation logic beyond direct mouse tracking.

Mouse Follower

A circle follows the mouse cursor within an SVG canvas, with its center position updating live to match the pointer's coordinates. The visualization uses React's `useState` and `useCallback` hooks to manage cursor tracking, while `ReactDOM` renders the SVG element and its circle to the page. The SVG's `onMouseMove` event handler captures the cursor position, and the circle's `cx` and `cy` attributes are updated accordingly with a fixed radius of 30 pixels.

Mouse Follower - D3 Data Vis Course

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The visualization uses React state to track mouse coordinates and re-render the circle’s cx and cy attributes. It imports the `arc` function from D3 but does not apply it, relying instead on React’s `onMouseMove` handler and D3 v5 for SVG rendering. The page is built with React 16.9 and renders a single unfilled circle at the pointer’s location.

Mouse follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The example demonstrates React state management with a `useState` hook and the `onMouseMove` event handler, which captures the cursor's client coordinates and passes them to the circle's `cx` and `cy` attributes. React re-renders the SVG element on each mouse movement, while D3's `arc` import is present but unused, and no external data source is involved.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time to mirror the pointer’s movement. The visualization uses React’s `useState` and `useCallback` hooks to track cursor coordinates (`clientX`, `clientY`) and re-render the circle’s `cx` and `cy` attributes on every mouse move. The SVG element handles the `onMouseMove` event, while the circle’s radius is fixed at 30 pixels. The code imports React, ReactDOM, and D3 v5, though no D3-specific functions are invoked beyond the library’s inclusion.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. Built with React, the app uses the `useState` hook to store the mouse coordinates and a `useCallback` handler triggered by the SVG's `onMouseMove` event. The circle is rendered as an SVG `<circle>` element with a fixed radius of 30 pixels. The viewport is set to 960 by 500 pixels, and the initial position is centered before any mouse movement occurs.

Mouse follower

A circle follows the mouse cursor within an SVG canvas, updating its center position in real time. The visualization uses React's `useState` and `useCallback` to manage mouse-move events, while the SVG `onMouseMove` handler captures pointer coordinates. The circle’s `cx` and `cy` attributes are bound to the state, and the scene is rendered via `ReactDOM.render` with a D3.js library import for potential data handling.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, centering itself on the pointer’s coordinates. The example demonstrates React state management to track mouse movement, updating the circle’s position on every move event. It uses React’s `useState` and `useCallback` hooks alongside D3 v6 for the SVG rendering, with an initial circle centered at 480, 250. The visualization responds interactively in real time, showcasing a minimal integration of React and D3 for dynamic graphics.
