An arrow follows the mouse cursor across the full viewport, rendered as an SVG path with a red marker arrowhead and thick stroke. The example demonstrates unidirectional data flow: a mousemove event triggers a state update that redraws the path. It uses D3 v7’s selection joins and `setState`/`render` pattern to update the SVG, with the path positioned relative to the cursor’s x and y coordinates.

Fork of Mouse Follower

A red arrow with a white fill follows the mouse cursor across a full-window SVG canvas. The arrowhead is defined in a marker with a custom path, and the arrow's curved path is calculated from the cursor's x- and y-coordinates. The example demonstrates unidirectional data flow using the d3.select and .join methods, where mousemove events trigger setState to update the state, and a new path attribute is rendered each time. It uses d3.v7 from unpkg and renders exclusively as SVG.

Arrow with Delay

A red arrow with a marker follows the mouse pointer, leaving a thin white trail behind it as the user moves across the screen. The visualization demonstrates unidirectional data flow: a `mousemove` event updates the state, which triggers a re-render of an SVG path using D3 v7. The path is drawn with a quadratic Bézier curve (`T` command) between offset coordinates, with its endpoint styled by an SVG marker definition. The code updates the `d` attribute on each render to reflect the latest cursor position.

Mouse Follower

A circular marker follows the mouse cursor across an SVG canvas, while a path traces the complete route of its movement. The visualization demonstrates unidirectional data flow in React with D3.js v5, using React state and Hooks (`useState`, `useCallback`) to handle mouse events and trigger re-renders. The path is built by collecting `clientX` and `clientY` coordinates on each `onMouseMove` event, and a reset button clears the trace back to the current cursor position. The SVG is rendered directly via React, with D3 providing the `path` utility for constructing the line string.

Mouse Follower

A circle follows the mouse pointer across the screen, updating its position in real time based on cursor movement. The visualization demonstrates unidirectional data flow with D3 v7 and React, where mouse events trigger state updates that re-render the circle’s coordinates. The code uses d3-selection `select` and `join` to bind SVG elements, with an initial state centered in the viewport. The React framework manages state through a `setState` callback, while the D3 `mousemove` event handler captures pointer positions.

Mouse Follower

A red square tracks the mouse across a full-screen SVG canvas. The visualization demonstrates unidirectional data flow using D3 v7's `select` and `join` pattern. A `mousemove` event on the SVG invokes a `setState` callback, which updates the state object with cursor coordinates and triggers a re-render, repositioning the 25×25-pixel rectangle. The `viz` function binds the state to the square's `x` and `y` attributes.

Mouse Follower

A red circle follows the mouse cursor across an SVG canvas, updating its position in real time as the user moves. Built with React and D3 v5, the app uses React’s `useState` and `useCallback` hooks to track mouse coordinates via the SVG `onMouseMove` event, then re-renders the circle’s `cx` and `cy` attributes accordingly. No data source is involved; the visualization simply demonstrates interactive event handling and state-driven rendering with SVG.

A black circle follows the mouse cursor across a green SVG canvas, responding instantly to pointer movement. The visualization uses React’s `useState` and `useCallback` hooks to track the mouse position and update the circle’s `cx` and `cy` attributes. The SVG element’s `onMouseMove` event handler captures the cursor coordinates, while D3’s `arc` module is imported but unused. The example demonstrates a simple interactive pattern combining React state management with SVG rendering.

Mouse Follower

A React-based SVG visualization tracks the mouse cursor with a single orange circle, updating its position in real time as the user moves across the viewport. The app uses React’s `useState` and `useCallback` hooks to manage the cursor coordinates, while D3’s `arc` import is included but unused. The circle renders via SVG inside a fixed 960×500 canvas, with the initial position centered before any mouse movement. The `onMouseMove` event handler on the `<svg>` element captures client coordinates and triggers a state update, seamlessly animating the follower through React’s rendering lifecycle.
