d3plus-shape

Fancy SVG shapes for visualizations

Installing

If using npm, npm install d3plus-shape. Otherwise, you can download the latest release from GitHub or load from a CDN.

import modules from "d3plus-shape";

d3plus-shape can be loaded as a standalone library or bundled as part of D3plus. ES modules, AMD, CommonJS, and vanilla environments are supported. In vanilla, a d3plus global is exported:

<script src="https://cdn.jsdelivr.net/npm/d3plus-shape@1"></script>
<script>
  console.log(d3plus);
</script>

Examples

Live examples can be found on d3plus.org, which includes a collection of example visualizations using d3plus-react. These examples are powered by the d3plus-storybook repo, and PRs are always welcome. 🍻

largestRect - An angle of zero means that the longer side of the polygon (the width) will be aligned with the x axis. An angle of 90 and/or -90 means that the longer side of the polygon (the width) will be aligned with the y axis. The value can be a number between -90 and 90 specifying the angle of rotation of the polygon, a string which is parsed to a number, or an array of numbers specifying the possible rotations of the polygon.
lineIntersection - Finds the intersection point (if there is one) of the lines p1q1 and p2q2.
path2polygon - Transforms a path string into an Array of points.
pointDistance - Calculates the pixel distance between two points.
pointDistanceSquared - Returns the squared euclidean distance between two points.
pointRotate - Rotates a point around a given origin.
polygonInside - Checks if one polygon is inside another polygon.
polygonRayCast - Gives the two closest intersection points between a ray cast from a point inside a polygon. The two points should lie on opposite sides of the origin.
polygonRotate - Rotates a point around a given origin.
segmentBoxContains - Checks whether a point is inside the bounding box of a line segment.
segmentsIntersect - Checks whether the line segments p1q1 && p2q2 intersect.
shapeEdgePoint - Calculates the x/y position of a point at the edge of a shape, from the center of the shape, given a specified pixel distance and radian angle.
largestRect - Simplifies the points of a polygon using both the Ramer-Douglas-Peucker algorithm and basic distance-based simplification. Adapted to an ES6 module from the excellent Simplify.js.

LargestRect - The returned Object of the largestRect function.

# new Image()

Creates SVG images based on an array of data.

a sample row of data

var data = {"url": "file.png", "width": "100", "height": "50"};

passed to the generator

new Image().data([data]).render();

creates the following

<image class="d3plus-Image" opacity="1" href="file.png" width="100" height="50" x="0" y="0"></image>

this is shorthand for the following

image().data([data])();

which also allows a post-draw callback function

image().data([data])(function() { alert("draw complete!"); })
