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 thresholds. The gradient is defined using an SVG `linearGradient` with multiple `stop` elements applied to the line’s stroke via `url(#line-gradient)`. The chart is built with D3 v7, using `d3.timeParse` for date formatting, `d3.scaleTime` and `d3.scaleLinear` for axes, and `d3.line` for the path geometry. Data is loaded from a CSV file with `d3.csv`, and the SVG output includes axis elements generated by `d3.axisBottom` and `d3.axisLeft`.

AI-generated description

This is a simple graph demonstrating the implimentation of a gradient on the line in a line graph.

This graph is part of the code samples for the update to the book D3 Tips and Tricks to version 7 of d3.js.

Line graph with gradient in v6

This line graph displays stock closing prices over time, with the line’s color gradient shifting from red to black to green based on the y-axis value. The gradient is defined using an SVG `linearGradient` with userSpaceOnUse coordinates and multiple stop points. The chart is built with d3.v6, using `d3.csv`, `d3.line`, `d3.scaleTime`, `d3.scaleLinear`, and `d3.axisBottom`/`d3.axisLeft`. Data comes from an external CSV file containing dates and closing prices.

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.

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.

Area graph with gradient in v7

This example shows an area graph with a custom gradient fill that transitions through red, black, and green zones, mapping stock closing prices over time from a CSV file. Using D3 v7, it parses dates and values, scales them with `d3.scaleTime` and `d3.scaleLinear`, and defines the area shape with `d3.area`. A `linearGradient` with multiple stops colors the area, while `d3.axisBottom` and `d3.axisLeft` render the axes. The SVG output is generated entirely with D3's data-join and path-generation methods.

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.

Area graph with gradient in v5

This example shows a time-series area chart of stock closing prices with a multi-color gradient that shifts from red through black to green based on the y-axis value. The area fills beneath the line, while the x-axis uses time scaling and the y-axis uses linear scaling. Built with D3 v5, it loads data from a CSV file and renders as SVG. The gradient is defined using an SVG `linearGradient` with `userSpaceOnUse` units, created via D3’s selection and data-join methods, and applied to a path generated with `d3.area`. Axis helpers `d3.axisBottom` and `d3.axisLeft` add the scales.

Using an 'if' statement in v7

This example shows a line graph of stock closing prices over time, with data points color-coded based on their value. The visualization uses SVG rendering and the d3.v7 library, specifically `d3.line`, `d3.scaleTime`, `d3.scaleLinear`, and `d3.axisBottom`/`d3.axisLeft`. It reads CSV data from `data.csv` via `d3.csv` and parses dates with `d3.timeParse`. Each data point is drawn as a circle whose fill color is determined by an `if` statement: values at or below 400 appear red, while higher values are black.

Area graph with gradient in v6

This example shows an area graph with a vertical gradient fill that transitions through red, black, and green bands, making the change in closing stock prices visually distinct. The gradient is defined using an SVG `linearGradient` element with `gradientUnits` set to userSpaceOnUse, and its stops are bound to explicit color and offset data. The area path is rendered with `d3.area()` using time-scaled x and linear-scaled y axes, while data from `data.csv` is parsed with `d3.timeParse`. Axes are drawn via `d3.axisBottom` and `d3.axisLeft`.
