A circular path is drawn as a gradient stroke that smoothly transitions through pink, purple, and back to pink, with a partially hidden segment indicated by a transparent gap. The example samples the SVG path uniformly using `getTotalLength` and `getPointAtLength`, then generates a series of quads and computes stroke outlines with custom line-join logic. Each quad is rendered as a separate filled SVG path, and its color is interpolated via `d3.interpolateRgbBasis`, with opacity controlled by the path position relative to the `complete` fraction. This technique produces a smooth, colorful gradient along the stroke without relying on SVG linear or radial gradients.

Gradient Along Stroke

This example shows a single thick SVG path rendered as a continuous gradient that transitions from green to red along the stroke, which can indicate directionality. Using the D3 v4 library, the code samples points uniformly along the path with `getPointAtLength`, then computes miter joints via line-line intersection for each segment. Each segment is filled and stroked with a color interpolated by `d3.interpolateRainbow` based on normalized path length, creating the gradient effect while avoiding antialiasing artifacts.

Gradient Along Stroke

This example shows a curved SVG path rendered as a continuous rainbow gradient that follows the stroke, with colors interpolated from green to red along the path’s length. The technique samples points along the path using the SVG `getPointAtLength` method, then computes miter joints via line-line intersection to fill each segment with a solid color from `d3.interpolateRainbow`. A thin stroke is added to each segment to avoid antialiasing artifacts. The code uses D3 v4 and renders entirely in SVG.

SVG Fundamentals Demonstration

This demo shows raw SVG path commands and gradient fills without a data source, using only the SVG element and its built-in path syntax. Three stroked paths use relative and absolute coordinates (M, L, l) to draw diagonal lines with varying thickness and color. A nested `<svg>` contains a linearGradient definition applied to an ellipse, demonstrating how gradients can be referenced via `url(#grad1)`. The example serves purely as a technical reference for SVG shape construction and styling.

Linear Gradient Along Line Path

A line chart maps ten points with a smooth cardinal curve, and a vertical linear gradient colors the stroke from red through yellow to green. The gradient is defined as an SVG `linearGradient` with five stops, rotated 90 degrees, and applied to the path’s `stroke` attribute. The color scale uses `d3.scaleLinear` with a five-color range, while `d3.line` and `d3.curveCardinal` generate the path geometry. The example demonstrates how to apply a multi-stop gradient along a line path using D3 v4 and SVG.

Radial Gradient

A full-window SVG renders a single circle that fills the viewport with a smooth transition from gold at the center to red at the edge. The visualization uses a `<radialGradient>` defined in the SVG `<defs>` section, with two `<stop>` elements specifying color and offset percentages. The circle references this gradient via the `fill` attribute using `url('#myGradient')`. This example is adapted from MDN documentation and demonstrates core SVG gradient functionality without any JavaScript or data processing.

Circle Gradient II

A single circle is centered on a blank SVG canvas, its fill defined by a radial gradient that transitions through three color stops. The gradient’s stops are mapped to a linear scale with a domain from -1 to 1, using the color range [#d73027, #e0e0e0, #4575b4]. This creates a smooth transition from red to light gray to blue. The example uses D3 v4’s `d3.scaleLinear` to map the domain values to the color range, and the SVG `radialGradient` definition to apply the gradient to the circle’s fill.

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.

Radial Gradient

This example demonstrates a radial gradient by rendering a single circle filled with a smooth transition from gold at its center to red at its edge. The SVG markup defines the gradient using a `radialGradient` element with two `stop` points, and applies it to the circle via the `fill` attribute referencing the gradient’s ID. The circle is positioned with a center at (5,5) and a radius of 5 within a 10×10 viewBox, rendering as a 960×300 SVG.
