A React-based SVG visualization renders a single circle at the center of a 960 by 500 canvas. The circle follows the mouse cursor in real time as the user moves it across the screen, using the `useState` hook to store the cursor’s x and y coordinates and the `useCallback` hook to handle the `onMouseMove` event. The React component updates the circle’s `cx` and `cy` attributes directly, with D3 v6 loaded but not used for this interaction. No external data is involved; the graphic demonstrates state-driven rendering and event handling in React.

Dataviz 3 - Interaction with React

A React-based SVG visualization demonstrates mouse interaction by rendering a single yellow circle that follows the cursor. The circle’s position updates on every `mousemove` event within the SVG element, using React’s `useState` hook to track coordinates and `useCallback` to optimize the handler. The app imports React and ReactDOM, renders an SVG of 960×500 pixels, and initializes the circle at the center. The code shows direct state-driven rendering without external data sources or animation libraries.

Interaction with React

This example demonstrates a React-based SVG visualization where a circle follows the mouse pointer across a 960-by-500 viewport. It shows how mouse events and unidirectional data flow manage interactive state in React, using the `useState` hook to track cursor coordinates and `useCallback` for the event handler. The single-circle rendering, with a white inner circle, updates its `cx` and `cy` attributes on every `onMouseMove` event, relying on D3 v6 for SVG utilities and React 16 for component rendering.

Interaction with React

This example demonstrates a real-time interactive visualization where a circular SVG element follows the mouse cursor across a 960x500 canvas. Built with React 17 and D3 v7, the application uses React’s `useState` and `useCallback` hooks to track mouse coordinates through an `onMouseMove` event handler on the `<svg>` element. As the pointer moves, React re-renders the circle’s `cx` and `cy` attributes, updating its position instantly. The visualization highlights how React manages state-driven updates for DOM elements, contrasting with D3’s imperative approach to data binding.

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.

Interaction with react

A circle follows the mouse cursor within an SVG canvas, demonstrating interactive state updates in React. The app tracks mouse movement via the `onMouseMove` event handler on the `<svg>` element and updates the circle’s `cx` and `cy` attributes using React’s `useState` hook. The visualization combines React 17 with D3 v7 for rendering, using a simple SVG `<circle>` element with a fixed radius. The code explicitly manages the circle’s position in React state rather than using D3’s data-binding, highlighting the interaction between React’s declarative model and SVG.

dv2020-ep14-viz14 - Mouse Follow

A circle follows the mouse as it moves over an SVG canvas. The visualization tracks the cursor’s client coordinates and updates the circle’s center position in real time. Built with React hooks (`useState` and `useCallback`), it handles mouse movement via the SVG `onMouseMove` event, re-rendering the circle’s `cx` and `cy` attributes. The example uses React 16.9 and ReactDOM for rendering, with a static SVG viewport of 960 by 500 pixels.

Interaction with React (Mouse Follower)

A circle follows the mouse cursor across an SVG canvas, updating its position in real time in response to pointer movement. The React state hook `useState` stores the current mouse coordinates, while the `onMouseMove` event handler updates that state through `setMousePosition`. The `useCallback` hook optimizes the event handler, and ReactDOM renders the component to the page. This example demonstrates how React manages interactive SVG rendering without any external data source or D3 dependency.

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.
