React Tech Radar

A react component that generates an interactive radar, inspired by thoughtworks.com/radar.

Demo (Storybook)

Installation

Using npm:

npm install --save react-tech-radar

Quick Start

import React from 'react';
import Radar from 'react-tech-radar';

function App() {

    const setup = {
        rings: ['adopt', 'trial', 'assess', 'hold'],
        quadrants: ['tools', 'techniques', 'platforms', 'languages'],
        data: [
            {
                name: 'D3',
                quadrant: 'tools',
                ring: "assess"

            },
            {
                name: 'TypeScript',
                quadrant: 'languages',
                ring: "trial"
            },
            {
                name: 'Storybook',
                quadrant: 'tools',
                ring: "adopt"
            }
        ]
    };

    return (
        <div className="App">
            <Radar {...setup} />
        </div>
    );
}

export default App;

Props Setup

The following 3 props should be configured in order to setup the tech radar:

  • quadrants
  • rings
  • data

data

data prop is an array of JSON elements representing the description of technologies.

Elements in the array should be in the following form:

Example:

{
data: [
          {
              name: 'D3',
              quadrant: 'tools',
              ring: "assess"
          },
          {
              name: 'TypeScript',
              quadrant: 'languages',
              ring: "trial"
          },
          {
              name: 'Storybook',
              quadrant: 'tools',
              ring: "adopt"
          }
      ]
}

quadrants

quadrants prop is an array of strings which represent slices of the circular radar. Any data element with the matching quadrant value goes into this slice

Elements in the array should be in the following form:

Example:

{
  quadrants: ['tools', 'techniques', 'platforms', 'languages']
}

rings

rings prop is an array of strings which represent at what level these technologies are adopted. For each element in rings, every quadrant is divided into rings. Innermost ring is the first element of the rings array and it usually represents the place for the most adopted technologies.

Example:

{
  rings: ['adopt', 'trial', 'assess', 'hold'],
}

Configuration Options

Prop Description Default Value
width The overall width of the main DOM element 700px
fontSize Font size of elements 12px
itemFontSize Set this if you want the items to have a different size than titles of quadrants and rings. If not set, defaults to fontSize 12px
colorScaleIndex A value from 0 to 5 for different collections of colors. See Storybook Color Schemes section for colors of each option. 5
radiusDiminish Radius of rings is not equal because of this constant. Each radius is x times greater than the outer one and x is this constant. 1.5

Prop Types

Radar.propTypes = {
    quadrants: PropTypes.array.isRequired,
    rings: PropTypes.array,
    data: PropTypes.array,
    width: PropTypes.number,
    fontSize: PropTypes.number,
    itemFontSize: PropTypes.number,
    colorScaleIndex: PropTypes.number,
    radiusDiminish: PropTypes.number
};

Storybook

You can see various states of the radar (such as color schemes, results of configurations, etc.) on the Storybook Page.

Google SpreadSheets Integration

If you want a very quick data integration, you can check out the Google Spreadsheets example.

The source code for the example is in 'examples' folder and also there is a running example in Storybook.

If you plug in this data you'll see this visualization

Sharing the sheet

  • In Google sheets, go to 'File', choose 'Publish to the web...' and then click 'Publish'.
  • Close the 'Publish to the web' dialog.
  • Copy the URL of your editable sheet from the browser (Don't worry, this does not share the editable version).

The URL will be similar to https://docs.google.com/spreadsheets/d/1waDG0_W3-yNiAaUfxcZhTKvl7AUCgXwQw8mdPjCz86U/edit. In theory we are only interested in the part between '/d/' and '/edit' but you can use the whole URL if you want.
