Mouse Moving

Mouse Move React

A React SVG visualization tracks the mouse position within a 960 by 500 viewport. It renders a single circle that follows the cursor, using React’s `useState` to store coordinates and `useCallback` to optimize the mouse-move handler. The circle’s center updates directly from the event’s `clientX` and `clientY` values, demonstrating a minimal interactive component built with React 16 and rendered through `ReactDOM.render`.

Mouse

A single black circle follows the mouse cursor across an SVG canvas, with its position updating reactively in real time. The circle’s center is driven by the `clientX` and `clientY` coordinates from the SVG element’s `onMouseMove` event, stored in React state via `useState` and `useCallback`. The visualization uses React 17 for rendering, D3 v7 for SVG utilities, and demonstrates a simple interactive pattern without any data source or external dataset. The circle radius is fixed at 30 pixels, and the SVG viewport is 960 by 500 pixels.

Mouse move

A single gray circle tracks the mouse cursor as it moves across a blank white SVG canvas. The circle’s center directly follows the pointer position, which is captured and stored in React state on every mouse-move event. This example uses React’s `useState` and `useCallback` hooks, along with `d3.v7` for SVG rendering, to update the circle’s `cx` and `cy` attributes in real time. No data source is involved; the visualization simply demonstrates interactive pointer tracking within a fixed 960×500 viewport.

Mouse Follower

A static SVG circle initially sits at the center of a 960×500 viewport, but its position is updated in real time through React’s `onMouseMove` event handler. The `handleMouseMove` function logs the cursor’s `clientX` and `clientY` coordinates to the console as the mouse moves across the container. Rendered with React 16.9 and D3 v7, the example demonstrates a minimal interactive pattern where the circle’s location could be tied to mouse input, though the code currently only captures and reports the coordinates.

Mouse Tracking

A circle follows the mouse cursor across an SVG canvas, with its position updating in real time as the pointer moves. The visualization uses React’s `useState` and `useCallback` hooks to track `clientX` and `clientY` coordinates from the `onMouseMove` event, rendering a single `<circle>` element via ReactDOM. D3 is loaded but not directly invoked; the rendering relies solely on SVG and React state management.

Mouse Events

A React application demonstrates mouse event handling by rendering a single SVG circle that follows the cursor across the viewport. The circle's position updates in real time through the `onMouseMove` event, which captures `clientX` and `clientY` coordinates and stores them in state via the `useState` hook. The `useCallback` hook optimizes the event handler. The visualization uses React 16.9 and renders directly to SVG, with the window dimensions determining the drawing area.

mouse movement

A single black circle tracks the user's mouse position across an SVG canvas, creating a simple interactive visualization. The application is built with React and D3 v7, using React's `useState` hook to store and update the mouse coordinates on every `mousemove` event. The circle's center (`cx` and `cy`) is bound directly to the state, and its radius is fixed at 30 pixels. The rendering is handled entirely through React's declarative SVG elements, with no D3 components used beyond the library's inclusion in the script tags.

Mouse

A black circle follows the mouse cursor across an SVG canvas, updating its position in real time. The example demonstrates React's `useState` and `useCallback` hooks to manage and update the circle's coordinates based on `mousemove` events, while D3.js v7 is loaded but not directly used. The visualization shows a minimal interactive pattern, where the circle moves fluidly with cursor movement and renders via React's declarative JSX syntax.
