justcharts

Just charts. Really.

The goal of this project is to make it incredibly easy to hack together a vegalite dashboard declaratively. The goal is that anything made in the vegalite editor can be copied into a static file with ease.

include

You can use jsDelivr to deliver the justcharts.js file via CDN. Note that you'll also need to have some vega dependencies around.

<script src="https://cdn.jsdelivr.net/npm/vega@5"></script>
<script src="https://cdn.jsdelivr.net/npm/vega-lite@5"></script>
<script src="https://cdn.jsdelivr.net/npm/vega-embed@6"></script>
<script src="https://cdn.jsdelivr.net/gh/koaning/justcharts/justcharts.js"></script>

usage

There are two main ways you can create just charts.

schema

You can create a vega based chart directly in html.

<vegachart schema-url="schemaone.json"></vegachart>

inline

Alternatively, you can also declare the vegalite-json definition inline in the vegachart component.

<vegachart style="width: 100%">
    {
        "data":{
            "url": "https://cdn.jsdelivr.net/gh/koaning/justcharts/bigmac.csv",
            "format": {
                "type": "csv"
            }
        },
        "mark": "line",
        "encoding": {
            "x": {"field": "date", "type": "temporal"},
            "y": {"field": "local_price", "type": "quantitative"},
            "color": {"field": "currency_code", "type": "nominal"}
        },
        "width": "container",
        "title": "hello there"
    }
</vegachart>

Note the "width":"container" setting. By doing this you're able to set the width/height of the chart directly from the <vegachart> html-style property. This is great for containers with relative widths.
