Fork of Random Circles

Random Circles

Fifty randomly positioned and sized circles drift across the browser viewport in this d3.v6 example. Each circle's location updates on a timer, shifting by small random increments at every tick, creating a subtle Brownian-like motion. The visualization uses the `d3.range` function to generate the initial dataset, `d3.select` to create the SVG canvas, and the `d3.timer` API to drive the animation loop. Circles are styled as steelblue fills via CSS, with a light gray page background.

Circles React

This example shows 50 randomly sized and positioned circles moving horizontally across the screen, bouncing off the edges. A button toggles between sorting the circles by descending radius and reverting them to random positions. Built with React hooks and D3 v5, it uses `d3.range` to generate the initial data and a `d3.timer` loop to update both React state and SVG attributes (`cx`, `cy`). The circles are rendered as SVG elements, with the animation driven by state changes that update the DOM.

Random circles

This example shows a dense field of overlapping circles rendered in an SVG, with their positions and colors appearing randomized across the display. Built with React, the component generates a triply-nested loop that creates circles using the `<circle>` element, calculating each `cx` and `cy` position by multiplying array values with `Math.random`. The fill color is derived from the array index arithmetic, producing a gradient-like effect in the RGB scale. The visualization relies on React’s `ReactDOM.render` to mount the SVG into the DOM, with no external data source.

Fork of Menu Part 1

This example creates 50 randomly sized and positioned circles on an SVG canvas using D3 v5 and React 16 hooks. The circles bounce horizontally across the screen via a `d3.timer` callback that updates their `cx` attributes each frame. A button labeled "Sort" reorders the circles by descending radius using a JavaScript state update, while a "Revert" button randomizes their positions again. It demonstrates integrating D3 selections with React's `useState` and `useEffect` for managing dynamic visual state.

This example shows a dense field of randomly positioned, semi-transparent rectangles and circles rendered with React and SVG, each with randomized stroke widths, opacity, and dynamically generated RGB colors. The layout is produced by a fixed array of 200 values calculated from a simple arithmetic formula, mapped through React components to create the visual elements. Using D3 v7 only to select the body and append a base SVG, the code primarily relies on React’s `ReactDOM.render` and custom components like `My_circle` to generate the shapes, with no interactive or animated behavior.

Circles Part2

Ten randomly placed light blue circles animate smoothly across the screen in a full-window SVG. The example uses React state to trigger a D3 v5 transition that shifts each circle horizontally; upon transition completion, new random x-coordinates are generated and the animation repeats. Data binding via `selectAll` and `join` keeps the circles synchronized with the changing state.

Fork of Menu Part 2

This example shows 50 randomly positioned and sized circles bouncing horizontally across the full screen, with a button to sort them by radius or revert to random positions. Built with React and D3 v5, it uses `d3.range`, `d3.timer`, and `d3.select` to manage SVG circle elements, while React state controls the circle data and re-renders on button clicks. The animation continuously updates the `cx` attributes as circles move, and the sort operation reorders the array before updating the DOM.

Circles

A field of 1,000 small circles drifts randomly across an SVG canvas, wrapping around the edges when they exit the viewport. A text label in the corner displays a live frames-per-second counter. The animation uses `d3.timer` to update each circle's `cx` and `cy` attributes every frame, with positions stored in a data array generated from `d3.range(1000)` and `Math.random`. The code runs on D3 v3 and renders purely with SVG elements.
