Two SVG panels sit side by side: one shows a static red square, the other renders a grid of points whose density is user-selectable. An animation updates the square’s x-coordinate at every timer tick, while a live FPS counter reveals how the update speed changes as the point count varies. The code uses D3’s `d3.svg.line` to generate a path from the grid data, and `setInterval` drives the square’s movement. A checkbox toggles whether points are placed inside the viewbox or shifted far outside, affecting rendering performance.

Update speed based on number of SVG elements in viewBox

A benchmark animates a red rectangle inside an SVG viewBox, while a grid of green circles is regenerated based on a user-selected count (500 to 10,000) and a toggle to place them inside or outside the viewBox. The animation updates the rectangle’s x-coordinate via `setAttribute` at maximum speed, and the visible FPS counter displays the resulting update rate. Using D3.js, it appends SVG circles based on the current `num_circles` and `inside` checkbox values, demonstrating how the number of rendered SVG elements affects rendering speed.

[separate SVG boxes ] Update speed based on number of SVG elements in viewBox

Two adjacent SVG boxes animate the movement of a red rectangle while displaying a live frame-rate counter. The performance benchmark is controlled through dropdown menus and a checkbox, allowing the user to adjust the number of green circles rendered inside the second viewBox and toggle whether they remain within it. The example uses d3.js selectors and data binding to update circle positions dynamically, while a setInterval timer drives the rectangle’s movement and calculates frames per second from timestamp differences.

Gist f4dd5c4b997e02efe9be

Four animated SVGs show a square deforming as its four corner points move along a continuously shrinking path. Each panel uses a different rule for selecting the next point: constant interpolation, gradually increasing step size, random step length, and a step inversely proportional to the remaining distance. The code relies on `d3.select`, `transition`, and `setInterval`, drawing line segments with `path` elements while updating point positions via the geometric helper functions defined in `geomtry.js`.

Animation

This example demonstrates the stark contrast between animated and static SVG rendering. The code appends a simple rectangle to the SVG canvas and repeatedly updates its x-coordinate with `setTimeout`, incrementing a counter every 10 milliseconds to create an infinite horizontal slide. Three linked versions allow comparison: one animates continuously, while two alternatives remove the update loop, leaving the rectangle fixed in place. The visualization uses raw D3.js selection and attribute methods (`svg.select("rect").attr`) rather than higher-level transition helpers, highlighting the fundamental mechanism behind frame-based movement in D3.

squares-around-circles

The animation shows a grid of small circles, each surrounded by four square outlines that continuously expand and rotate. The squares appear to “breathe,” pushing outward and then resetting in a cyclical loop, creating a pulsing, geometric pattern across the screen. The code uses D3.js with SVG paths, leveraging the `transition` and `attrTween` methods for smooth movement. Each square’s position and orientation are calculated from its center point and a side number, updated via functions like `pushLinesOut` and `pointToPath`. The data is generated procedurally, with no external dataset.

Moving Dots

Animated dots move in a wave-like pattern across an SVG canvas, with their count oscillating between five and fifteen over time. The visualization uses D3’s `select`, `range`, and data joins with `join()` to efficiently create, update, and remove circle elements each frame. A `setInterval` at 60 frames per second updates a time variable that drives both the vertical sine-wave motion and the changing number of dots, rendering in React with D3 version 6. The background is blank, focusing solely on the dynamic positioning of the circles.

Data Update Section

A grid of blue circles continuously updates in real time as their vertical positions and radii oscillate based on a sine wave function. The animation runs at 60 frames per second via a JavaScript `setInterval`, with each frame regenerating the dataset using `makeData` and passing it to `vizData`. D3 v5 handles the data join and SVG rendering, while the circles cycle through magenta and cyan color transitions using chained D3 transitions with ease functions. The example demonstrates dynamic data binding and stateful animations with ES6 module imports.

setInterval

A 10×10 grid of circles animates smoothly, with each circle’s radius oscillating according to a sine wave that shifts over time. Built with React and D3 v7, the visualization uses `setInterval` to update the frame every 16.6 milliseconds, generating new data via `Math.sin` and binding it through `selectAll` and `.join`. The SVG rendering redraws all circles each tick, with black fills and positions determined by row and column spacing.
