# Chart.js Graphs Dot Parser

[![NPM Package][npm-image]][npm-url] [![Github Actions][github-actions-image]][github-actions-url]

Helper package for [chartjs-chart-graph](https://github.com/sgratzl/chartjs-chart-graph) for parsing DOT files and generate
the data structure for the chart.js plugin.

Input:

```dot
graph {
    a -- { b c d };
    b -- { c e };
    c -- { e f };
    d -- { f g };
    e -- h;
    f -- { h i j g };
    g -- k;
    h -- { o l };
    i -- { l m j };
    j -- { m n k };
    k -- { n r };
    l -- { o m };
    m -- { o p n };
    n -- { q r };
    o -- { s p };
    p -- { s t q };
    q -- { t r };
    r -- t;
    s -- z;
    t -- z;
}
```

## Install

```bash
npm install --save chart.js chartjs-chart-graph chartjs-chart-graph-dot-parser
```

## Usage

see [Samples](https://github.com/sgratzl/chartjs-chart-graph-dot-parser/tree/master/samples) on Github

CodePens

- [Simple Dot File](https://codepen.io/sgratzl/pen/TODO)

## Supported Dot Features

graph types: `graph`, `digraph`

graph attributes:

- `label` ... set as dataset label

node attributes

- `label` ... set the node label
- `color` ... set as node border color
- `fillcolor` ... set a node background color
- `shape` ... only supports: `circle`, `diamond`, and `box`

edge attributes (note: only works with the 3.0.x version of the chartjs-chart-graph plugin due to renaming)

- `color` ... set as edge line/border color
- `penwidth` ... set as edge line/border width

## Development Environment

```sh
npm i -g yarn
yarn set version 2
yarn
yarn pnpify --sdk
```

### Building
