Kloia TechRadar

Motivation

At Kloia, we maintain a public Tech Radar to help our consultants 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.

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: // entries coming from config.json
    // ...
  ]
});

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/

How did we deploy it?

We use Cloudflare Pages to deploy our Tech Radar. It's an basic static site hosting service that is free with unlimited bandwidth. It automatically builds and deploys the site from the "master" branch of this repository whenever we push a change. There's no need to configure anything.

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

As a working example, you can check out docs/index.html — the source of our public Tech Radar.
