You should see a chart being rendered below.
It is generated with the following code:
<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>
<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": "dollar_price", "type": "quantitative"},
"color": {"field": "currency_code", "type": "nominal"}
},
"width": "container",
"title": "this is a simple demo"
}
</vegachart>
The <vegachart>
element is generated by a small library called justcharts.js
. You
can give it a json object as contents and the <vegachart>
element will parse it to
create a vegalite chart. You can learn more about the vegalite json specification on
the documentation page but you can also
explore it interactively.
Note that you can also use the .to_json()
output from altair
to generate the json for these chart elements.
It's meant to make it easy to hack together html-dashboards. It doesn't need a build tool in node, it merely needs an html file. This is great when you want to rapid prototype a dashboard or if you want to make a public dashboard with github pages.
