Two rectangles demonstrate a reusable D3 linearGradient definition, created in an SVG `defs` element. The first rectangle fills its interior with a diagonal red-to-blue gradient, while the second applies the same gradient to a four-pixel stroke, leaving its fill empty. Using d3-selection and d3 v5, the code sets `x1`, `x2`, `y1`, and `y2` attributes on the gradient and appends offset `stop` elements to control color transitions. The example shows how one gradient can style both fill and stroke in the same SVG scene.

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.

Linear Gradient

This example demonstrates a full-screen rectangle filled with a diagonal linear gradient. The gradient transitions from a solid green color at the top-left corner to a solid red color at the bottom-right corner, using the `pad` spread method. The visualization is rendered as SVG, constructed with the D3.js v3 library. It uses `d3.select` to append an `svg` element, defines a `linearGradient` inside a `defs` block with two `stop` elements, and applies the gradient as a fill via a URL reference.

SVG_fundamentals

This example demonstrates two SVG rectangles with rounded corners, each filled using a linear gradient. The first rectangle uses a gradient defined by CSS classes within the SVG `<style>` block, while the second uses an inline gradient definition. Both gradients transition from red through transparent black to blue. The code relies on native SVG elements (`<defs>`, `<linearGradient>`, `<stop>`, `<rect>`) and CSS styling, with no external JavaScript libraries. The rendering is pure SVG embedded directly in the HTML document.

fresh block

This example demonstrates a simple gradient-filled rectangle drawn in an SVG canvas. It shows a black horizontal bar with a linear gradient that fades from fully opaque on the left to nearly transparent on the right, positioned near the top of the frame. The code uses D3 v4 to select the body, append an SVG element, and construct a linearGradient definition with two stop points via `selectAll` and `data`. A single `rect` is then appended and styled with the gradient, relying on D3's data-binding to set offset and opacity values.

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.

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.

HTML Starter

This example shows a single vertical bar whose fill color transitions through a five-stop gradient from red to green, with the bar’s height fixed and width constant. The data array contains one number (39) that currently does not affect the bar’s dimensions, despite the readme suggesting otherwise. The code uses d3.select and append to create an SVG, then builds a linearGradient with d3’s data join, binding the colors array to stop elements. The bar is a rect with a fill referencing the gradient, rendered against a light gray background.

SVG Fundamentals

This example demonstrates core SVG fundamentals using four primitive shapes: a circle with a red-to-blue radial gradient, a larger circle with a centered radial gradient, a blue-outlined rectangle, and a red line. The SVG markup defines two radialGradient elements within a defs block, using stop tags to specify color transitions. A linearGradient is also declared but not referenced by any shape. The 800x400 canvas is rendered directly in HTML, with gradients using the url(#id) reference syntax.
