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()`.

Gradient Encoding

This line chart shows daily temperature readings over a year, using a linear gradient as a redundant color encoding alongside the y-axis position. The gradient spans from steelblue at cooler temperatures through gray to red at warmer ones, making temperature ranges immediately visible. The code uses d3.svg.line with basis interpolation to draw the path, while d3.svg.axis creates the time and temperature axes. The gradient is defined with `gradientUnits` set to `userSpaceOnUse`, positioning color stops at explicit y-coordinates from the d3.scale.linear output, applied via the stroke attribute referencing the SVG linearGradient element.

Line graph with gradient in v4

This example shows a line graph of stock closing prices over time, with the line colored by a vertical gradient that shifts from red to black to green based on price levels. The visualization uses d3.v4 to load CSV data, parse dates with `d3.timeParse`, and render an SVG path via `d3.line`. A `linearGradient` with multiple stop points is applied to the line’s stroke, and axes are added using `d3.axisBottom` and `d3.axisLeft`. The data is drawn from `data.csv` containing date and close values.

Colour gradient on a graph line

This example shows a line graph of stock closing prices over time, with the line colored by a red-to-black-to-green gradient that maps to the y-axis value. The graph uses D3.js (version 3.5.17) with SVG rendering, and applies the gradient via a `linearGradient` definition referenced by the line’s `stroke` attribute. Data is loaded from a CSV file using `d3.csv`, and axes are generated with `d3.svg.axis`. The gradient stops are explicitly defined in code to create color bands at 40% and 62% of the vertical range.

Simple Line Chart with Color Gradient

This interactive line chart visualizes daily temperature readings from a Noe Valley sensor, using a color gradient that shifts from steelblue to gray to red to encode temperature values. The chart groups data by day, with buttons allowing users to toggle between different days. Built with D3.js and moment.js, the SVG visualization relies on `d3.time.scale` for the time axis and a linearGradient element for the temperature color encoding. The data originates from the Data Canvas project and is displayed for a slice of the full time series.

Area Gradient fill

This chart shows daily temperature variations over a year with a line and a gradient-filled area beneath it. The area uses a vertical gradient that shifts from steel blue to gray to red, tied to specific temperature thresholds. Built with the D3.js library, it parses dates from a CSV file and uses `d3.svg.area` to generate the path representing the temperature data between the line and the chart’s baseline.

Threshold Encoding

This line chart displays daily temperature readings over a year, changing color from black to red as the value crosses a 50-degree threshold. A linear gradient with two stops at the same offset creates the hard color break. The visualization uses the D3.js v3 API, including `d3.time.scale`, `d3.scale.linear`, `d3.svg.axis`, and `d3.svg.line`, with data loaded from a TSV file. The SVG rendering applies the gradient to the line path.

Line Chart

This example visualizes temperature over time with a line chart. The SVG rendering plots a line and points connecting daily temperature readings, with axes and tick labels generated from the data. Built with React and D3 v5, it uses `scaleLinear` for scaling, `line` from D3 for the path, and `timeFormat` for tick labels. The data is loaded as CSV from a remote URL using D3's `csv` utility, and React state manages the asynchronous data fetching.

Line chart.js!

This example uses D3.js to render a line chart from a remote CSV file of employee data, plotting monthly temperatures. The visualization first loads the data with `d3.csv`, parses the numeric fields, and then builds an SVG chart with `d3.scaleLinear` for the x- and y-axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and a `d3.line` generator to draw the temperature trend. The chart is rendered as an SVG with axes positioned using margins, while the line itself is styled in steel blue.
