    Fork of https://github.com/evmar/webtreemap

    Usage

    Web

    The data format is a tree of Node, where each node is an object in the shape described at the top of tree.ts.

    Add the contents of [src/styles-to-add.css] to your stylesheets.

    <script src='webtreemap.js'></script>
    <script>
    // Container must have its own width/height.
    const container = document.getElementById('myContainer');
    // See typings for full API definition.
    webtreemap.render(container, data, options);

    Options

    Option Type Default
    padding [number, number, number, number] [14, 3, 3, 3]
    lowerBound number 0.1
    applyMutations (node: Node) => void () => void
    caption (node: Node) => string (node) => node.id
    showNode (node: Node, width: number, height: number) => boolean (_, width, height) => (width > 20) && (height >= options.padding[0])
    showChildren (node: Node, width: number, height: number) => boolean (_, width, height) => (width > 40) && (height > 40)
    Option Description
    padding In order: padding-top, padding-right, padding-bottom, padding-left of each node
    lowerBound Lower bound of ratio that determines how many children can be displayed inside of a node. Example with a lower bound of 0.1: the total area taken up by displaying child nodes of any given node cannot be less than 10% of the area of its parent node.
    applyMutations A function that exposes a node as an argument after it's dom element has been assigned. Use this to add inline styles and classes. Example: (node) => { node.dom.style.color = 'blue' }
    caption A function that takes a node as an argument and returns a string that is used to display as the caption for the node passed in.
    showNode A function that takes a node, its width, and its height, and returns a boolean that determines if that node should be displayed. Fires after showChildren.
    showChildren A function that takes a node, its width, and its height, and returns a boolean that determines if that node's children should be displayed. Fires before showNode.

    Development

    The modules of webtreemap can be used both from the web and from the command line, so the build has two layers. The command line app embeds the output of the build into its output so it's a bit confusing.

    Run yarn run build to compile TS -> build/JS (as esm) and then run rollup to make the dist (iife).

    Run yarn run build:demo to create a public/index.html demo page.

    Run yarn watch to use entr to do build:demo on a watchloop.
