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.

Mouse Follower Simple

This example shows a single circle following the mouse cursor as it moves across the browser window. The visualization uses D3 v7 to create an SVG canvas sized to the viewport and appends a circle element at an initial position. Through D3's event handling, the `mousemove` listener updates the circle's `cx` and `cy` attributes based on the cursor's coordinates, producing a direct and immediate tracking effect.

Mouse Follower Simple

This example demonstrates a simple interactive visualization where a circle follows the mouse cursor within an SVG container. The circle’s position is stored in the application state, and every mouse movement updates the state using immutable update patterns, spreading the previous state object and assigning new x and y coordinates. The code uses D3’s `select` and `pointer` APIs to handle the `mousemove` event, and a data join to render the SVG and circle elements. The circle is initialized at the center of the container before any mouse interaction occurs.

Mouse Follower Simple

A simple interactive visualization renders a circle that follows the mouse cursor. The circle grows in radius as the user moves the mouse faster, measured via the `event.movementX` and `event.movementY` properties, with its size capped at 100 pixels. The example uses D3 v7's selection and data join methods (`select`, `selectAll`, `join`) to bind SVG elements, updating position and radius on each `mousemove` event. The circle is styled with a transparent fill and a black stroke, demonstrating dynamic SVG updates with D3.

Mouse Follower

A circle inside an SVG follows the mouse cursor in real time. The visualization tracks pointer coordinates and updates the circle's position instantly. Built with React and D3 v7, the app uses the `onMouseMove` event and the `useState` hook to store and render the cursor's `clientX` and `clientY` values. The circle's radius is fixed at 30 pixels.

Mouse Follower

A simple interactive visualization renders a single circle that follows the mouse cursor across an SVG canvas. The circle’s position updates in real time, tracking the user's pointer movement. The example uses React’s `useState` and `useCallback` to manage the mouse coordinates, and renders the circle via an SVG `<circle>` element with `cx` and `cy` attributes set from the current mouse position. The `onMouseMove` event handler on the SVG element captures the cursor's `clientX` and `clientY` values, which are then used to update the circle’s location.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The visualization is built with React and D3 v6, using React's `useState` and `useCallback` hooks to track and update the mouse coordinates from the `onMouseMove` event. The circle is rendered as an SVG element with a fixed radius, and its `cx` and `cy` attributes are bound to the current mouse position. The example demonstrates a simple interactive pattern in a React-D3 integration.

Fork of Mouse Follower Simple

A simple interactive visualization demonstrates a circle following the mouse cursor across a full-screen SVG canvas. The example uses D3 v7, selecting the SVG element and appending a circle with an initial position of (50, 50) and radius of 50. The `mousemove` event listener updates the circle's `cx` and `cy` attributes to match the mouse coordinates. This minimal code showcases D3's event handling and attribute manipulation for direct, real-time interaction without any data-driven elements.

Mouse follower

This example demonstrates a mouse-follower visualization: a circle that tracks the cursor’s position across an SVG canvas. The circle moves continuously as the user moves the mouse, with its center coordinates updated from the event’s `clientX` and `clientY` values. The implementation uses React’s `useState` and `useCallback` hooks to manage and update the mouse position, while the `<svg>` element’s `onMouseMove` handler triggers the state change. The rendering is done via SVG, with a single `<circle>` element whose `cx` and `cy` attributes are bound to the current position. D3 is loaded but not used for interaction or data processing.
