This example demonstrates that text placed along a path can smoothly transition between different arc geometries using D3.js's standard transition mechanism. It shows a repeating animation where the arc's endpoints and radius change, causing the text "Yay, my text is moving back & forth" to follow the newly defined path each time. The visualization relies on SVG's `<textPath>` element, linked to a `<path>` via the `xlink:href` attribute, and uses D3's `.attr("d", ...)` with `.transition().duration()` to animate the path data. The code also references D3 transitions with the `.each("end", repeat)` callback to loop the animation indefinitely.

AI-generated description

This is an example from my blog on Placing Texts on Arcs with D3.js that shows that a transition between similar paths (two arcs in this case) can be accomplished by the standard .transition().duration()

Another version shows how to transition between more complex paths

Animated textPath

This example animates a blue arc expanding while the text “Hello, curved textPath!” follows its path. The code uses d3.svg.arc with interpolated angles and a transition.attrTween on the path’s “d” attribute. Two WebKit workarounds are shown: selecting textPath by class and repeatedly resetting its xlink:href attribute to force redraw. The SVG includes a path and textPath element, with the text appearing scrunched at the start due to the technique’s limitations.

Animated Clipped textPath

This example animates an SVG path while simultaneously clipping curved text against it, so the text appears to draw itself along the arc. A blue arc path transitions over five seconds using `transition.attrTween` with a `d3.svg.arc` generator, while a `<textPath>` references a static hidden path and a `clipPath` uses the animated path via a `<use>` element. The code relies on D3 v3, SVG, and a 960×500 viewport, with the text “Hello, curved textPath!” clipped to the moving path’s shape.

text path example

This example demonstrates how to render text along curved SVG paths using D3 v4. Two dashed, tomato-colored paths are drawn on a light gray canvas, and each path serves as the baseline for a line of text. The text elements are anchored at the midpoint of their respective paths using `text-anchor: middle` and `startOffset: 50%`, with steel-blue fill from the CSS. The visualization shows how D3’s `d3.line()` with `curveBasis` can generate smooth, arbitrary paths, and how SVG's `<textPath>` reuses those paths to align text along the curves, illustrating a simple technique for creating curved typography.

animated arc

This example animates a set of orange arc segments that expand and fade out over time, creating a wave-like effect. The visualization uses SVG paths generated by the `d3.arc` generator, with a `clipPath` (a 200×200 rectangle) to constrain the arcs' visibility. A single transition, invoked via `transition.attrTween`, interpolates each arc's inner and outer radii from 0 to 300, while `style("opacity", 0)` fades them out. The animation runs over 4 seconds with staggered delays of 200 milliseconds per arc, using `d3.easeLinear`. Ten arcs are created from an array of empty objects, and the code relies on D3 v4.

Text Path example d3 v4

This example demonstrates interactive text along a draggable path using D3 v4 and SVG. It shows how text can follow a curved path defined by a `d3.line` with a `d3.curveBasis` curve, while the path itself is editable through drag events. The initial path is a circular arc, and users can modify the text via an input field. The code uses D3’s `drag` behavior, `path.attr("d")`, and `textPath` to update both the curve and the text position dynamically.

Text Along a Path

This example shows how to place text along a curved path using SVG’s `textPath` element. A visible gray curve is defined in the SVG `<defs>` section, and the sentence "We go up, then we go down, then up again." follows that path via an `xlink:href` reference. The code uses D3 v3 to build the SVG structure, appending a `<path>`, a `<text>` with a `<textPath>`, and a `<use>` element to display the curve.

Animated Arcs

Four colored arc segments rotate continuously around a central point, changing their start and end angles to new random positions every few seconds. The animation uses D3 v4’s `d3.interval` to trigger periodic updates, and each transition relies on `transition.attrTween` with a custom `arcTween` function that interpolates between angle values using `d3.interpolate`. The SVG paths are generated by a `d3.arc()` generator, with each arc assigned a fixed inner and outer radius, forming concentric rings. The data is procedurally generated JavaScript, with random start angles and arc lengths derived from a random score.

Arc Tween

The visualization demonstrates smooth animated transitions of arc segments using D3 v4’s `transition.attrTween`. It shows a circular foreground arc that repeatedly updates its angle, while a secondary set of colored arcs animates inward and outward between paired data values. The `d3.arc` generator builds SVG path strings with bound start/end angles, and the tween interpolates the endAngle over 750 milliseconds for the main arc and 1750 milliseconds for the colored segments. Random angle targets drive the main arc, while paired arrays (e.g., `[0, 0.25, 0.4, 0.65, 0.9, 1]`) control the secondary arcs’ expansion and contraction.
