A single dark circle tracks the mouse cursor across an SVG canvas. The visualization uses React’s `useState` and `useCallback` to manage the cursor’s coordinates, with an `onMouseMove` event handler updating the circle’s `cx` and `cy` attributes in real time. The circle’s radius is fixed at 30 pixels, and the SVG viewport is 960 by 500 pixels. The code initializes the mouse position to the canvas center before any interaction.

Interaction With React, mouse follower

A red circle follows the cursor inside an SVG canvas in this React-based interactive visualization. The example demonstrates a mouse-follower interaction using React's `useState` hook to track pointer coordinates and update the circle's `cx` and `cy` attributes in real time. The `App` component renders an SVG element with an `onMouseMove` event handler, which calls `setMousePosition` on each pointer movement. The circle’s position is bound to the stored mouse coordinates, creating a direct visual response. The code uses React 16.9.0, ReactDOM, and the SVG `circle` element, with the canvas sized at 960 by 500 pixels.

8.00 Mouse Follower

A single dark circle moves within an SVG viewport in direct response to the mouse cursor. The example demonstrates a simple React state update mechanism: the `onMouseMove` event on the `<svg>` element captures cursor coordinates, which are stored in `mousePosition` via `React.useState` and applied to the circle’s `cx` and `cy` attributes. The initial position is centered at (480, 250), and the circle’s radius is set to 10% of the viewport height. Crafted with React 17 and ReactDOM, it renders a pure SVG without external data or animation libraries.

Interaction with React: Mouse follower

A circle follows the mouse cursor within an SVG canvas. The example uses React's `useState` and `useCallback` to track the cursor's `clientX` and `clientY` coordinates, updating the circle's `cx` and `cy` attributes on every `onMouseMove` event. The SVG and circle are rendered directly through ReactDOM, with no D3 visualization logic, though the D3 library is loaded in the page. The interaction is purely event-driven, with the initial circle position centered at width/2, height/2.

Interaction with React

A circle follows the cursor as it moves across an SVG canvas. The example demonstrates how React manages interactive state for a simple visualization, using the `useState` and `useCallback` hooks to track mouse coordinates and update the circle's position. React 16.9 renders the SVG element, which listens for `onMouseMove` events and updates the `cx` and `cy` attributes of the circle in real time.

Interactive react

A single dark circle follows the cursor across a full-screen SVG canvas, reacting instantly to every mouse movement. The visualization uses React 16.9 with the `useState` and `useCallback` hooks to track pointer coordinates, updating the circle's `cx` and `cy` attributes via ReactDOM rendering. The example demonstrates React's declarative approach to interactive graphics, with the `onMouseMove` event handler on the root SVG element driving all state changes in real time.

7.-Mouse Follower (React)

A bright circle trails the user's pointer as it moves across an SVG canvas, resetting to the canvas center on load. The React app tracks mouse coordinates with `useState` and an `onMouseMove` event handler, updating the circle’s `cx` and `cy` attributes. It uses D3 v7 for SVG rendering within a React 17 UMD setup, with the circle’s position bound directly to the pointer’s client coordinates.

Mouse Follower

A single dark circle follows the mouse cursor across an SVG canvas in a React-based visualization. The circle’s position updates live via React’s `useState` hook, driven by the SVG `onMouseMove` event, which captures the cursor’s client coordinates. Rendering uses plain SVG elements, with D3 v5 loaded but not actively used in the logic. The example demonstrates reactive state-driven updates in React for interactive graphics, with the circle centered on the pointer’s exact location.

Mouse Follower

This example demonstrates a simple interactive visualization where a circle follows the mouse cursor within an SVG canvas. It shows how React state can track pointer position and update visual elements in real-time. The code uses React’s `useState` and `useCallback` hooks to manage the mouse coordinates from the `onMouseMove` event, and renders a single circle element with dynamic `cx` and `cy` attributes. The visualization is built with React 16.9 and rendered as SVG, with the circle starting at the center of a 960×500 pixel viewport.
