Chart Configuration
The server uses Chart.js configuration format. Here's a basic example:
{
"type": "bar",
"data": {
"labels": ["January", "February", "March"],
"datasets": [{
"label": "Sales",
"data": [65, 59, 80],
"backgroundColor": "rgb(75, 192, 192)"
}]
},
"options": {
"title": {
"display": true,

}
}
}
URL Generation
The server converts your configuration into a QuickChart URL:
https://quickchart.io/chart?c={...encoded configuration...}
