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 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.

Fork of Mouse Follower Simple

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 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.

A circle follows the mouse across a full-screen SVG, shifting to a random color from a predefined palette on every movement. The example uses D3 v7's selection methods, including `svg.on('mousemove')` for event handling and `circle.attr` to update position. An initial `getColor()` function picks randomly from an array of seven colors, while CSS hides page margins and overflow. The visualization demonstrates basic interactive SVG rendering with D3's data-binding approach.

A white circle follows the mouse cursor across a solid blue-gray background. The example uses D3 v7 to select the `#app` container, append an SVG canvas sized to the browser window, and create a single circle element. A `mousemove` event listener updates the circle’s `cx` and `cy` attributes with the event coordinates, providing direct, real-time feedback. The visualization is rendered entirely through SVG, with styling applied via an external CSS file.

A blue rectangle and a text label reading "Follow Mouse" both track the cursor across an SVG canvas that fills the viewport. The page listens to mouse movement events and updates the x and y coordinates of both elements in real time. Built with D3 v7, the example uses selection methods like `append`, `attr`, and `on` to create and move the shapes. The SVG is sized to the browser window, and CSS hides page margins to maximize the tracking area.

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 circle follows the mouse cursor within an SVG canvas, responding to every movement by updating its center coordinates. This example uses React’s `useState` to track the pointer position and D3’s `arc` (though not directly applied), with the SVG’s `onMouseMove` event triggering a state update that repositions the circle. The visualization runs inside an HTML page that imports React and D3 via CDN, rendering through `ReactDOM.render`.
