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.

Fork of Mouse Follower

A circle follows the mouse cursor across a full-screen SVG canvas, updating its position through a unidirectional state flow. The `viz.js` module listens for `mousemove` events on the SVG and calls `setState` to store the cursor’s x and y coordinates, which are then passed back as props to re-render the circle’s `cx` and `cy` attributes. Using D3 v7’s `select` and data joins, the code binds a single circle element to the state, demonstrating a simple reactive pattern where the view is a pure function of the current state.

Fork of Mouse Follower

This example demonstrates a mouse follower where a circle visually tracks the cursor’s position across the viewport, serving as a minimal illustration of unidirectional data flow in a React-driven D3 visualization. The code uses D3’s `select` and `join` API to incrementally build an SVG and circle element, updating their `cx` and `cy` attributes based on mouse events. State changes trigger a re-render through the `setState` callback, with the initial position defaulting to the center of the window.

Fork of Mouse Follower (some experiments)

A circle follows the mouse cursor within a full-window SVG canvas. The example demonstrates unidirectional data flow in React, where the mouse position is the data. The circle’s center coordinates are set from the current state, initialized to the window’s center. The code uses D3’s `select` API to manage the SVG and circle elements, and RDP’s `viz` and `setState` functions to handle rendering and state updates in response to `mousemove` events.

A yellow circle follows the mouse cursor across the full browser viewport. The visualization demonstrates unidirectional data flow in a React-like pattern: mouse movement triggers a `setState` callback that updates position coordinates, which are then rendered as circle attributes. Using D3 v7, the `viz` function binds an SVG element and updates `cx` and `cy` properties based on the current state. The initial position defaults to the viewport center before the first mouse interaction.

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.

Fork of Mouse Follower Simple

A simple interactive visualization demonstrates a circle following the mouse cursor across a full-screen SVG canvas. The example uses D3 v7, selecting the SVG element and appending a circle with an initial position of (50, 50) and radius of 50. The `mousemove` event listener updates the circle's `cx` and `cy` attributes to match the mouse coordinates. This minimal code showcases D3's event handling and attribute manipulation for direct, real-time interaction without any data-driven elements.

Mouse Follower

A single black circle follows the cursor across a full-screen SVG canvas, updating its position in real time. The visualization demonstrates a minimal state-driven D3 render loop, where a `mousemove` event listener calls a `setState` function to update the pointer coordinates. The `viz` function uses a data join to create and update the circle element, with `d3.select` handling the SVG selection and attribute updates for the x and y positions. The example relies on D3 v7 and a custom render pattern that re-renders the entire visualization on each state change.

Fork of Mouse Follower Simple

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.
