English | 简体中文

What is F6

F6 is a mobile graph visualization engine, which provides a set of basic mechanisms, including rendering, layout, analysis, interaction, animation, and other auxiliary tools. F6 aims to simplify the relationships, and help people to obtain the insight of relational data.

Developers are able to build graph visualization analysis applications or graph visualization modeling applications easily.

Powerful Animation and Interactions

Features

  • Abundant Built-in Items: Nodes and edges with free configurations;
  • Steerable Interactions: More than 10 basic interaction behaviors ;
  • Powerful Layout: More than 10 layout algorithms;
  • Convenient Components: Outstanding ability and performance;
  • Friendly User Experience: Complete documents for different levels of user requirements. TypeScript supported.

F6 concentrates on the principle of 'good by default'. In addition, the custom mechanism of the item, interation behavior, and layout satisfies the customazation requirements.

Abundant Built-in Items

Installation

$ npm install @antv/f6

Usage

import F6 from '@antv/f6';
import graphData from './data';
import dagreLayout from '@antv/f6/dist/extends/layout/dagreLayout';
import TreeGraph from '@antv/f6/dist/extends/graph/treeGraph';

F6.registerLayout('dagreLayout', dagreLayout);
F6.registerGraph('TreeGraph', TreeGraph);

Page({
  data: {
    width: 300,
    height: 400,
    pixelRatio: 1,
  },
  onLoad() {
    const { windowWidth, windowHeight, pixelRatio } = my.getSystemInfoSync();
    this.setData({
      width: windowWidth,
      height: windowHeight,
      pixelRatio: pixelRatio,
    });
  },
  onCanvasInit(ctx, rect, canvas, renderer) {
    this.graph = new F6.TreeGraph({
      context: ctx,
      renderer,
      width: this.data.width,
      height: this.data.height,
      linkCenter: true,
      modes: {
        default: ['drag-canvas', 'zoom-canvas'],
      },
      defaultNode: {
        size: 40,
      },
      layout: {
        type: 'compactBox',
        direction: 'RL',
        getId: function getId(d) {
          return d.id;
        },
        getHeight: () => {
          return 26;
        },
        getWidth: () => {
          return 26;
        },
        getVGap: () => {
          return 20;
        },
        getHGap: () => {
          return 30;
        },
        radial: false,
      },
    });

    this.graph.node(function (node) {
      return {
        label: node.id,
      };
    });

    this.graph.data(graphData);
    this.graph.render();
    this.graph.fitView();
  },
  onTouch(e) {
    this.graph.emitEvent(e);
  },
  onUnload() {
    this.graph?.destroy()
  }
});

Development

$ npm install

# lerna bootstrap for multiple packages
$ npm run bootstrap

# build the packages
$ npm run build:all

# if you wanna watch one of the packages, e.g. packages/core
$ cd ./packages/core
$ npm run watch

# run test case
$ npm test

# run test case in watch mode
npm test -- --watch ./tests/unit/algorithm/find-path-spec
DEBUG_MODE=1 npm test -- --watch ./tests/unit/algorithm/find-path-spec
