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.

Linear Gradient

Two horizontal SVG rects demonstrate linear gradients: a static HTML/SVG version with hardcoded stops and a dynamic D3 v4 version using `d3.scaleLinear` for the color range. The D3 code programmatically appends `stop` elements to a `linearGradient` definition, mapping five color values across offsets from 0% to 100%. Both rects are stroked in black, and the example contrasts explicit markup with data-driven gradient creation. The gradient fills are applied via the `fill` attribute referencing the gradient IDs, with the D3 version relying on the `d3-selection` API to construct the SVG structure.

Chart with Gradient

A minimal D3.js line-area chart displays nine data points of arbitrary x-y values, with the area fill transitioning from dark gray to red via an SVG linearGradient. The chart includes labeled axes with tick marks, axis arrows, and a title. The code uses d3.scale.linear for scaling, d3.svg.area to generate the filled path, and d3.svg.axis for the axes, all rendered as SVG elements.

d3v4 - Gradient Color Line Chart

This example shows a line chart of temperature data over time, where the line’s color shifts through a red-gray-steelblue gradient based on value. The chart uses d3.v4's `d3.line()` with `d3.curveStep` to generate a stepped path, and a `linearGradient` with three `stop` elements, defined in SVG `defs`, applies the color scale via the `stroke` attribute. The data is loaded from a CSV of temperature readings, with x/y axes scaled using `d3.scaleLinear()`.

Line (using curveCardinal)

A line chart uses a cardinal spline to connect six predefined data points across an SVG canvas. The d3.line generator with the curveCardinal interpolation produces a smooth, curved path through the points, which are also marked as circles on the chart. The rendering relies on D3 v4’s selection and attribute methods to assign the generated path data to the SVG path element.

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.

Line graph with gradient in v5

A line graph displays stock close prices over time, with the line colored by a vertical gradient that shifts from red to black to green based on the y-axis value. The example uses d3.csv to load date and close data, d3.timeParse for date formatting, and d3.scaleTime/scaleLinear for axes. A linearGradient element with multiple stop offsets is applied via the stroke URL reference, while d3.line generates the path and d3.axisBottom/axisLeft render the scales. The SVG output is built entirely with D3 v5.

gradient path

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.

Gist bb8fddc4a5fc3cc60c99

A line chart maps a small array of ten numbers to an SVG path, showing how the values fluctuate across a linear sequence. The visualization uses a red, unbroken polyline to emphasize the shape of the data, with the y-axis scaled from the data’s minimum to maximum and the x-axis evenly spaced by index. The code creates the chart using d3.scale.linear for both axes and d3.svg.line to generate the path, which is appended to an SVG container via d3.select and datum. The fixed width and height of 500 pixels define the plotting area, while the stroke and fill styles come from a CSS class.
