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 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 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 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.

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.

Fork of Mouse Follower

A circle follows the mouse cursor across a full-viewport SVG. The example demonstrates unidirectional data flow: mouse events trigger a state update, which then re-renders the visualization. Built with D3 v7, it uses `select`, `join`, and event handlers to bind the circle’s `cx` and `cy` attributes to the current cursor position. The state is managed externally and passed into the `viz` function, with `setState` triggering a re-render on each mouse move. No external data source is used; the interaction is purely based on user input.

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.

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

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.
