Forked from D3Path

This example demonstrates two fundamental D3.js path generators: `d3.line` and `d3.arc`. A black polyline connects four data points, with commented-out curve options like `d3.curveCardinal` and `d3.curveBasis` showing alternative interpolation methods. Beside it, three arc segments rendered via `d3.arc` form a partial donut chart with varying inner radii, fill colors, and a pad angle, all drawn as SVG paths on a 1600x800 canvas.

D3Path

D3Path demonstrates two fundamental D3.js geometry primitives rendered as SVG paths. The left side plots a polyline through four explicit data points using `d3.line()`, with commented-out curve options (`d3.curveCardinal`, `d3.curveBasis`, etc.) illustrating alternative interpolation strategies. The right side draws three concentric arc segments using `d3.arc()` with varying radii (`innerRadius`, `outerRadius`), angles, and padding (`padAngle`) to produce multi-colored pie-like wedges. The example uses hardcoded JavaScript arrays for data and D3 v6 directly from the unpkg CDN, with an SVG canvas sized 1600x800, showcasing basic path construction without external styling.

path with d3 - 1

A simple SVG line chart demonstrates D3's `d3.line()` path generator. Five coordinate pairs define a polyline rendered as a thick black path across a 960 by 500 canvas. A green circle with a CSS hover animation (class `pulseCircle`) sits at the first data point, scaling from zero to four times its size over two seconds using keyframes. The example shows D3 v7 appending SVG elements and generating path data from an array of points, with the circle's interactive pulse effect driven by vanilla CSS rather than D3 transitions.

D3.js| Path

The example displays a collection of primitive shapes and line types in an SVG canvas using D3.js v4. It shows circles, rectangles, and various path elements, including arcs drawn with the `arc()` function and lines generated by `d3.line()` and `d3.path()`. The visualization uses D3’s selection, data-binding with `.datum()`, and data-driven loops via `.data()` and `.enter()` to create elements from an array of values. The SVG background is green, with a GeeksforGeeks header, and all shapes are rendered statically without interaction.

Basic path and line with d3

This example demonstrates two fundamental SVG shapes—a closed path and a line—rendered with D3 version 7. The code appends an SVG element using `d3.select` and `svg.append`, then draws a path defined by arc (`A`) and quadratic Bézier (`Q`) commands, followed by a straight line with explicit `x1`, `y1`, `x2`, and `y2` attributes. The path’s `d` attribute is set using a template literal, while the line uses chained `.attr` calls for positioning and stroke styling.

Basic shapes

This example demonstrates a collection of fundamental D3.js shapes, including circles, rectangles, arcs, lines, and paths, all rendered as SVG elements on a canvas. It showcases various ways to construct these shapes, such as using the `d3.arc` function for annular sectors, `d3.line` for splines, and data-driven bindings with `.datum()` and `.data()`. The scene also includes programmatically generated rectangles with a purple fill, a pink circle, and a custom path created via `d3.path`. A small CSV dataset is linked but not directly used. The code relies on D3 v6 for shape creation and SVG manipulation.

shapes

This example demonstrates how to generate a smooth, curving line path in D3 version 7 using the `d3.line` generator with the `curveCardinal` interpolation. The code defines an array of six coordinate points and passes them to the generator, whose output is then assigned to an SVG `<path>` element via the `attr` method. The visualization runs entirely in an SVG renderer with a single path displaying the resulting curved shape on a 2000x2000 canvas. The example highlights a minimal, direct approach to converting raw coordinate data into a visual shape.

D3 Path Examples

This example demonstrates how D3.js can draw and animate SVG paths from simple coordinate datasets, including diagonal and horizontal lines, multipoint curves, triangles, and rectangles. The code defines multiple data arrays and uses the `d3.svg.line()` API with various interpolation types to render static shapes, while separate functions animate paths by transitioning the `d` attribute using `transition().duration(6000)`. One animation elongates a horizontal line by mutating the dataset’s endpoint, and another shifts the line’s origin point, both relying on D3’s built-in transition system. The page sets its frame height to 1800 pixels to accommodate the multiple SVG canvases.

d3 curve

This example shows a green curve rendered through an SVG path, connecting four user-defined points using D3’s line generator with the natural cubic spline interpolation. The curve’s shape is computed from the point coordinates, which are explicitly set inside the JavaScript code. D3.v5 is used to build the path data, while the path is appended to an `<svg>` element with the ID `svg1`. The page also includes a separate canvas element, though it is not involved in this rendering. The code references `getPointAtLength` to inspect the path geometry.
