Fork of Mouse Follower

A circle follows the mouse pointer, changing to a random color and opacity with each movement. The visualization uses unidirectional data flow, where a state object is updated on mouse events and passed to a rendering function. Built with D3.js v7, it uses `select` to manage an SVG and circle element, while custom `randColor` and `randOpacity` functions generate random values.

Fork of Mouse Follower that Changes Color

A circle follows the mouse across an SVG canvas, changing color with each click. The visualization uses D3's `select`, `selectAll`, and `join` methods to declaratively manage the SVG circle element, tracking mouse position and color state in an external `state` object. Rendering is driven by unidirectional data flow: `setState` updates the state and triggers a re-render, which applies the new `cx`, `cy`, and `fill` attributes to the circle.

A single gray circle follows the mouse cursor across a full-screen SVG canvas, creating a direct and immediate visual link between pointer movement and graphical output. The example uses d3-selection to append an SVG circle and attach a `mousemove` event listener to the SVG element, updating the circle’s `cx` and `cy` attributes with the event’s x and y coordinates. Rendered in a browser via a minimal HTML page, it demonstrates fundamental D3 v7 selection, event handling, and attribute manipulation.

A single circle follows the mouse pointer across a full-screen SVG. The example demonstrates basic D3 event handling and shape manipulation, using a selection created with `d3.select` and attribute updates on the `mousemove` event. The circle’s `cx` and `cy` coordinates are directly set to the event’s `x` and `y` values, with no animation or interpolation. The SVG canvas is sized to the browser window via `window.innerWidth` and `window.innerHeight`, and the CSS hides page margins and scrollbars.

A circle, rectangle, and text label all follow the mouse cursor across the screen, while a separate set of draggable circles is rendered using D3's data join and drag behavior. Clicking anywhere on the SVG appends a new circle with a random radius from the `d3.range` array, colored via `d3.schemePastel1`. The code uses D3 v7 selections and event handlers (`svg.on("mousemove")`) to update SVG attributes (`cx`, `cy`, `x`, `y`) in real time, with `d3.drag()` enabling interactive circle repositioning.

A single gray circle follows the mouse cursor across an SVG canvas that fills the browser window. The demonstration shows how D3 v7 event handling can drive direct attribute updates on SVG elements. The code appends an SVG and circle using d3.select and selection.append, then listens for mousemove events on the SVG, updating the circle’s cx and cy coordinates from the event’s x and y properties. No external data source is used; the visualization relies purely on user interaction with the rendered vector graphic.

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.

A simple interactive visualization demonstrates pointer tracking by rendering a single circle that follows the mouse cursor across the full browser window. The SVG canvas fills the viewport using `window.innerWidth` and `window.innerHeight`. D3's `selection.on('mousemove', ...)` event listener updates the circle's `cx` and `cy` attributes to the cursor's coordinates. The example uses D3 v7's `select` to append and style the SVG and circle elements, showcasing basic event handling and attribute manipulation.
