以下是您要翻译的代码部分:

function seqToBurstData(originalData, circleKeys){
    const sunBurstData = [];
    const valuePath2pointId = {}; // auxiliary data used to identify the parent id of a point

    // get all the values for {dataPoint} from top key to {level} key, joined by '_'
    // used to index nameLevel2pointId data, to ensure each point has a unique index value
    const valuePath = (dataPoint, level) =>
        Array.from({length: level}, (_, i) => dataPoint[circleKeys[i]]).join('_');

    circleKeys.forEach(function(key, index){
        const level = index + 1;
        let currentValuePath = null, nValues = 0, sunBurstPoint;
        for(const o of originalData){
            const thisValuePath = valuePath(o, level);
            if(thisValuePath !== currentValuePath){

                sunBurstPoint = {
                    id: level + '.' + nValues, // scheme similar to Highcharts examples for sunburst
                    parent: level === 1 ? null : valuePath2pointId[valuePath(o, level - 1)],

As a start point you can use this function (I changed a little bit the data to see more effects):

// used to index nameLevel2pointId data, to ensure each point has a unique index value
const valuePath = (dataPoint, level) =&gt;
Array.from({length: level}, (_, i) =&gt; dataPoint[circleKeys[i]]).join(&#39;_&#39;);
circleKeys.forEach(function(key, index){
const level = index + 1;
let currentValuePath = null, nValues = 0, sunBurstPoint;
