有了这个json数据，我怎么把它转换成这个
[
{
name: "Agriculture",
data: [0,0,0,1,1,0,0,0,39]
},
{
name: "Aviation",
data: [1,0,0,0,0,0,0,0,0]
},
{
name: "Beauty & Wellness",
data: [0,0,0,0,0,1,0,0,2]

{

{

data: [0,1,0,0,0,0,0,0,0]

{

}
{
name: "Waste Management",
data: [0,0,0,0,1,0,0,0,4]
}
]
我尝试了以下方法：
let countryData = data.Industries.map(country => country.Country)
document.write(JSON.stringify(countryData))
let industryData = data.Industries.map(industry => {
return industry.Data.map(i => {
return i.Industry
})
})
let flatIndustry = industryData.flat(Infinity).sort()
let filterIndustry = flatIndustry.filter((a, b) => flatIndustry.indexOf(a) === b)
let getCount = data.Industries.map(industry => {
return industry.Data.map((i, index) => {
return i.Count
})
})
注意：结果行业数据将被排序，并将检查每个国家/地区是否存在该特定行业，如果不存在，则在排序的行业值上附加零 (0) 或前置 (0)。 我在堆积条形图中使用这些数据
