FusionCharts是一款功能強大的圖表庫，用于創建交互式和動態的圖表。使用JSON數據是一種流行的方法，可以將數據與FusionCharts一起使用。以下是在FusionCharts中使用JSON數據的基本步驟：

const dataSource = {
"chart": {
"caption": "Monthly revenue",
"subCaption": "2019",
"xAxisName": "Month",
"yAxisName": "Revenue (in USD)",
"numberPrefix": "$",
"theme": "fusion"
},
"data": [
{
"label": "Jan",
"value": "420000"
},
{
"label": "Feb",
"value": "810000"
},
{
"label": "Mar",
"value": "720000"
},
{
"label": "Apr",
"value": "550000"
},
{
"label": "May",
"value": "910000"
},
{
"label": "Jun",
"value": "510000"
},
{
"label": "Jul",
"value": "680000"
},
{
"label": "Aug",
"value": "620000"
},
{
"label": "Sep",
"value": "610000"
},
{
"label": "Oct",
"value": "490000"
},
{
"label": "Nov",
"value": "900000"
},
{
"label": "Dec",
"value": "730000"
}
]
};
const chartConfig = {
type: "column2d",
width: "100%",
height: "400",
dataFormat: "json",
dataSource: dataSource
};
FusionCharts.ready(function () {
var chart = new FusionCharts(chartConfig);
chart.render();
});

以上代碼展示了使用JSON數據在FusionCharts中創建一個基本的柱狀圖。將數據對象分配給dataSource變量，該對象包含用于呈現圖表的圖表設置和數據數組。然后，將數據源變量傳遞給chartConfig的dataSource屬性，以便將數據傳遞到chartConfig對象。最后，在chart.render（）方法中呈現圖表。
