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.

AI-generated description

This is a simple graph demonstrating the implimentation of a gradient on the line in a line graph. This was written using d3.js v4 and is a follow on to the simple graph example here.

This graph is part of the code samples for the update to the book D3 Tips and Tricks to version 4 of d3.js.

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.

Line graph with gradient in v7

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`.

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.

Area graph with gradient in v4

This example shows an area graph of stock closing prices over time, with a custom gradient applied to the fill to create a color-coded visualization of price levels. The graph uses d3.area() to generate the area path and d3.scaleTime() and d3.scaleLinear() for the axes. A linearGradient element is appended to the SVG, with stop colors set to red, black, and lawngreen at various offsets, creating distinct bands. Data is loaded from a CSV file using d3.csv() and parsed with d3.timeParse().

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 graph with v4

This simple line graph displays the daily closing value of a stock over a month, using data from a CSV file. The SVG chart is built with D3.js v4, employing `d3.scaleTime` and `d3.scaleLinear` to map dates and prices, while `d3.line` generates the path. The axes are drawn with `d3.axisBottom` and `d3.axisLeft`, and the line is styled with a steel-blue stroke.

Simple line graph with v4

A simple SVG line graph plots the closing price of a stock over time, using data from a local CSV file ordered by date. It demonstrates basic D3 v4 setup with margins, time and linear scales, and an axis. The chart uses `d3.line`, `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft`. Style and stroke are defined via CSS. The example serves as a minimal starting point for building more complex visualizations.

Simple line graph with v4

A simple line graph shows the closing price of a dataset over time, with dates on the x-axis and values on the y-axis. Using d3.v4, the code loads a CSV file via `d3.csv`, parses dates with `d3.timeParse`, and constructs the line with `d3.line`. SVG scales and axes are built with `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft`. The rendered SVG path displays a steelblue line, with margins and dimensions set explicitly.
