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.

A mouse finder which the circle will enlarge when the user moves the mouse faster.

Mouse Follower Simple

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

This example demonstrates a mouse-following circle that changes position with cursor movement and shifts to a random color on click. The visualization starts with a blue circle centered in the viewport, then uses d3’s `select`, `pointer`, and `join` methods to render an SVG and update its attributes. State changes follow immutable update patterns, spreading the previous state and overriding specific properties like `x`, `y`, and `color`. The code also relies on container dimensions and event listeners for `mousemove` and `click` interactions.

Mouse Follower

A single black circle follows the cursor across a full-screen SVG canvas, updating its position in real time. The visualization demonstrates a minimal state-driven D3 render loop, where a `mousemove` event listener calls a `setState` function to update the pointer coordinates. The `viz` function uses a data join to create and update the circle element, with `d3.select` handling the SVG selection and attribute updates for the x and y positions. The example relies on D3 v7 and a custom render pattern that re-renders the entire visualization on each state change.

Mouse Follower

A circle tracks the cursor across a full-screen SVG canvas. Each mouse movement updates the circle’s center coordinates via a state object and a custom `setState` callback. The visualization uses d3.v7’s `select` API to bind SVG elements and handle `mousemove` events, while `join` synchronizes the circle’s `cx` and `cy` attributes. The canvas resizes to the browser window dimensions.

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 as the pointer moves. The visualization uses React state to track mouse coordinates via the `onMouseMove` event handler and renders a single `<circle>` element with D3 v7’s selection-free React integration. The SVG viewport is fixed at 960 by 500 pixels, and the circle’s center tracks the clientX and clientY values directly.
