A mouse follower displays the text "Click to change the color!" that tracks the cursor’s position across the screen. Clicking triggers a transition that enlarges the font size and updates the text to show the new random RGBA color value. The visualization uses D3.js v7 with unidirectional data flow, managing state through a `setState` function and re-rendering on each interaction. Mouse movement and click events update the state, while D3 transitions animate the text’s size and color display.

AI-generated description

A mouse follower with the text "Click to change the color!" using unidirectional data flow.

On click, the color of the text changes and it displays the rgba of the color with transition (bigger font size).

Mouse Follower that Changes Color

A D3.js v7 circle of radius 50 follows the mouse cursor, changing its fill color to a random RGB value each time the user clicks. The visualization demonstrates unidirectional data flow from mouse events through a state object that stores the current x, y, and color coordinates. Built with D3's `select` and `join` APIs, it renders an SVG inside the `#app` container, updating the circle's `cx`, `cy`, and `fill` attributes on every state change.

Mouse Follower That Changes Color

A circle follows the mouse cursor across a full-screen SVG canvas, changing its fill color to a random RGB value on each click. The visualization demonstrates unidirectional data flow with a state object managed by `setState`, while D3 v7 selections and the `join` pattern handle SVG rendering. Mouse position events trigger state updates through `svg.on('mousemove')`, and color changes use `svg.on('click')` with random `rgb()` generation. The example uses d3.select and d3's data join to bind single elements.

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.

Color Changing Mouse Follower

A circle follows the mouse cursor across the canvas, and a click randomly changes its fill color. The visualization demonstrates a unidirectional data flow pattern using D3 v7, where mouse events update a state object which then triggers a re-render of the SVG. It uses D3's `select` and `.join` operations to efficiently create and update the circle element, while the rendering logic resides in a separate `viz.js` module. The circle's position and color are driven entirely by the state managed through a custom `setState` function.

Mouse Follower

This example demonstrates a single semi-transparent circle that follows the mouse cursor across a light green background, changing color randomly with each click. The visualization uses D3’s `mousemove` event and `d3.pointer` to update the circle’s position, while a `click` event triggers a random hex color assignment. The circle’s coordinates and fill are stored in a state object, and D3’s data join (`selectAll`/`join`) binds this state to the SVG circle element. The rendering approach relies on direct SVG manipulation via D3, with no external data source—purely interactive and state-driven.

Mouse Follower

A small, randomly colored circle follows the mouse cursor across a full-screen SVG canvas, changing to a new random color with every mouse movement. Built with D3, the code uses `select` to append an SVG element sized to the window, a `circle` element for the follower, and the SVG `on('mousemove')` event to update the circle's `cx`, `cy`, and `fill` attributes. No data source is used; the visualization is purely interactive, with the color generated via a custom `getRandomColor` function.

Mouse Follower with Colorful Circles

A mouse follower creates an expanding circle at the cursor position, with each circle fading out and disappearing after 2 seconds. The circles use the `d3.schemePaired` color scale to generate varied stroke colors. Built with React and D3 v5, the app tracks mouse movement via React’s `onMouseMove` event and appends SVG circles using `d3.select` with a `transition()` duration of 2000ms that animates the radius and stroke opacity.

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.
