Motivation

At Zeal, we maintain a a tech radar to help our engineering teams align on technology choices. It is based on the pioneering work by ThoughtWorks.

This repository contains the code to generate the visualization: radar.js (based on d3.js v4). Feel free to use and adapt it for your own purposes.

Latest radar: https://lotto24.github.io/tech-radar/

Usage

1. include d3.js and radar.js:

<script src="https://d3js.org/d3.v4.min.js"></script>
<script src="radar.js"></script>

2. insert an empty svg tag:

<svg id="radar"></svg>

3. configure the radar visualization:

radar_visualization({
  svg_id: "radar",
  width: 1450,
  height: 1000,
  colors: {
    background: "#fff",
    grid: "#bbb",
    inactive: "#ddd"
  },
  title: "My Radar",
  quadrants: [
    { name: "Bottom Right" },
    { name: "Bottom Left" },
    { name: "Top Left" },
    { name: "Top Right" }
  ],
  rings: [
    { name: "INNER",  color: "#93c47d" },
    { name: "SECOND", color: "#b7e1cd" },
    { name: "THIRD",  color: "#fce8b2" },
    { name: "OUTER",  color: "#f4c7c3" }
  ],
  print_layout: true,
  entries: [
   {
      label: "Some Entry",
      quadrant: 3,          // 0,1,2,3 (counting clockwise, starting from bottom right)
      ring: 2,              // 0,1,2,3 (starting from inside)
      moved: -1             // -1 = moved out (triangle pointing down)
                            //  0 = not moved (circle)
                            //  1 = moved in  (triangle pointing up)
   },
    // ...
  ]
});

Entries are positioned automatically so that they don't overlap.

Local Development

1. install dependencies with yarn (or npm):

yarn 

2. start local dev server:

yarn start

3. your default browser should automatically open and show the url

http://localhost:3000/
