This example animates the morphing of one SVG path into another using D3’s `transition.attrTween` and a custom path interpolation function. The path alternates between two cubic Bézier shapes in an infinite loop, with each transition lasting two seconds and using uniform distance sampling for smooth point-by-point interpolation. The code references `d3.select`, `d3.active`, and `getTotalLength`, while importing D3 v6 from a CDN. The included `province.csv` file contains COVID-19 statistics for Chinese provinces, though it is not loaded or visualized in the rendered output.

Path Tween

This example demonstrates smooth path interpolation between two SVG shapes defined by cubic Bézier curves. A black path morphs between two distinct configurations over a two-second animated loop, using SVG’s getPointAtLength and getTotalLength methods to uniformly sample points at four-pixel intervals. The transition replaces the original curve with a polyline for interpolation via d3.interpolate, then restores the Bézier path upon completion. The animation runs in d3 v4 with transition.attrTween, alternating between the two path definitions indefinitely.

Path Tween

This example shows a smooth animated transition between two SVG path shapes, alternating back and forth indefinitely. The code samples both the source and target paths uniformly using the SVG `getPointAtLength` method, then interpolates the corresponding points to create a piecewise linear curve during the transition. After each cycle, the path is restored to its original cubic Bézier form. The animation uses D3 v4’s `transition.attrTween` and `d3.easeLinear` easing, with a precision of 4 pixels for sampling.

SVG path animation

This example animates the stroke of SVG path elements to create a continuous drawing effect. It uses D3.js (v3) with a queue to load an external SVG file containing complex path data, then applies an infinite, looping transition. The animation interpolates the `stroke-dasharray` attribute using `d3.interpolateString` and `transition.attrTween`, calculating the path’s total length with `getTotalLength()` to reveal each path progressively. The paths are styled with CSS, setting a black stroke on a transparent fill.

This example shows how D3.js can animate transitions between two different datasets, displayed as orange circles along a horizontal axis. The circles’ radii and horizontal spacing are derived from each dataset’s values, and a button toggles between the two arrays. The implementation uses `transition()` to animate the circles’ `cx`, `cy`, and `r` attributes over 500 milliseconds. The code relies on D3’s selection and `.enter()`/`.exit()` methods to add or remove circles when the dataset changes, with SVG elements for rendering.

Named Transitions

This example demonstrates concurrent transitions on a single SVG path by using named transitions in D3 3.5. A black cross-shaped symbol, rendered with a red stroke, rotates continuously via the “twizzle” transition while its stroke width pulses with the “plonk” transition. Each animation uses `transition.attrTween` and `transition.style` with `d3.interpolateString`, and recursively reschedules itself with `each` and `transition.duration` to create an ongoing, non-interfering loop.

SVG path animation

A red dot animates along a black, wiggly SVG path, looping infinitely. The path is defined in an external SVG file. Built with D3.js v3, the visualization loads the SVG via `d3.xml`, extracts the path with a `d3.select`, and uses a `transition.attrTween` to move a circle marker based on `getPointAtLength` and `getTotalLength`, replicating Mike Bostock’s point-along-path interpolation example.

Spline Transition

A path of normally distributed random data, rendered as a smooth basis-interpolated line, continuously scrolls leftward as new points append and old ones shift off. The animation loops by chaining transitions with `d3.active` and `transition.on`, updating the `d` attribute via `d3.line` before translating the SVG path. A `clipPath` rect hides the sliding tangent change at the edges. The example uses d3.v4, random samples from `d3.randomNormal`, and SVG axes with `d3.axisBottom` and `d3.axisLeft`.

A black cubic Bézier path is drawn on an SVG canvas using D3 v4, with its total length queried via `getTotalLength()`. The example marks two points sampled along the path at 50% and 78% of its length, using `getPointAtLength()` to position small red and blue circles. A green line is then constructed between the two points and extended backwards to the canvas edge, demonstrating how to compute a secant line from arbitrary positions along a vector path. The visualization uses inline SVG elements created through D3's selection API, with styling applied via a linked CSS file.
