Circles with random color picker

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.

Use 'return' in React App

A random radial pattern of colored circles radiates outward from the center of an SVG canvas, with each circle’s size and hue varying unpredictably. The React component `Circles` renders individual `<circle>` elements, while `index.js` generates 50 x-positions and 50 pixel offsets to compute coordinates using trigonometric functions (`Math.cos` and `Math.sin`). Fill colors are derived from the index values and random multipliers, and circle radii multiply a fixed base by `Math.random()`. ReactDOM renders the app into the root element, with `Circles.js` exporting a stateless functional component.

React Starter

This example shows a grid of circles rendered in an SVG, where each circle’s position and color are generated from nested loops over an array of integers. The React app uses `ReactDOM.render` to mount an SVG element, with circle positions determined by multiplying array values by `Math.random()`, and fills set via RGB values derived from the loop index. It relies on React 16.10 and ReactDOM, producing a randomized pattern without external data sources.

Circles Pack

This visualization shows a large grid of concentric circles arranged in a repeating pattern across an SVG canvas. The circles are drawn with green outlines, a stroke width of 8, and 0.8 opacity, creating a dense, mosaic-like texture. The code uses React to render the SVG elements, with a custom `Circles` component that wraps the native SVG `<circle>` element. It generates 20 distinct radii and maps them over a 5×5 grid of positions, scaling the entire group by 0.4. ReactDOM mounts the tree to the DOM, and the page uses the UMD production builds of React 16.10.0.

Circles with Math.random and fill with jsx

This example displays a scatter of small circles generated from random positions. Each circle’s vertical coordinate comes from `Math.random()`, while its horizontal position and color are derived from an array of sequential numbers. The visualization uses React to render an SVG, mapping over a precomputed array to create circle elements. The code explicitly uses `Math.random()`, React’s `ReactDOM.render`, and JSX inside an `<svg>` container with a `g` transform, producing 201 circles with RGB fills based on their array index.

Circles Pack

This example displays a tightly packed grid of red, empty circles arranged in a square formation across an SVG canvas. The visualization generates 10 rows and 10 columns of circles, each with a fixed radius, positioned at regular intervals. React components produce the circles, while the code manually constructs arrays for positioning and radius calculations without using external data libraries. The circles use SVG properties such as opacity, stroke color, and fill to render the final pattern.

React Starter

This example displays a dense scatter of overlapping circles on a grey SVG canvas, with positions and fill colors randomly derived from nested array mappings. Built with React and ReactDOM, the visualization renders three levels of map operations over a numeric array, generating circles with radii of 10 pixels and RGB values computed from the loop index. The SVG output uses the `id='svg'` element with a fixed 960×500 viewport, while color intensity scales with the square of the array value.

Circles Effect at the junctions

A grid-based visualization renders 960 small square cells across an SVG canvas, each colored with a random red-blue value to create a scattered circle-like effect at the junctions where cells meet. The code uses React 16.10 to generate the layout, mapping over arrays of coordinates to place every rectangle individually. The SVG elements are drawn with the `rect` API, and the fill color is computed dynamically using `rgb()` with a random multiplier. A larger square border outlines the overall composition, while the grid cells themselves use no stroke, producing a seamless visual pattern.
