我正在尝试重新创建分组条形图示例，但我更喜欢 JSON 数据，而不是使用 CSV:
var data = [
{
"State": "CA",
"Under 5 Years": 2704659,
"5 to 13 Years": 4499890,
"14 to 17 Years": 2159981,
"18 to 24 Years": 3853788,
"25 to 44 Years": 10604510,
"45 to 64 Years": 8819342,
"65 Years and Over": 4114496
},
{
"State": "TX",
"Under 5 Years": 2027307,
"5 to 13 Years": 3277946,
"14 to 17 Years": 1420518,
"18 to 24 Years": 2454721,
"25 to 44 Years": 7017731,
"45 to 64 Years": 5656528,
"65 Years and Over": 2472223
},
{
"State": "NY",
"Under 5 Years": 1208495,
"5 to 13 Years": 2141490,
"14 to 17 Years": 1058031,
"18 to 24 Years": 1999120,
"25 to 44 Years": 5355235,
"45 to 64 Years": 5120254,
"65 Years and Over": 2607672
},
{
"State": "FL",
"Under 5 Years": 1140516,
"5 to 13 Years": 1938695,
"14 to 17 Years": 925060,
"18 to 24 Years": 1607297,
"25 to 44 Years": 4782119,
"45 to 64 Years": 4746856,
"65 Years and Over": 3187797
},
{
"State": "IL",
"Under 5 Years": 894368,
"5 to 13 Years": 1558919,
"14 to 17 Years": 725973,
"18 to 24 Years": 1311479,
"25 to 44 Years": 3596343,
"45 to 64 Years": 3239173,

"5 to 13 Years": 1345341,
"14 to 17 Years": 679201,

"25 to 44 Years": 3157759,
"45 to 64 Years": 3414001,
"65 Years and Over": 1910571
}
]
这是我尝试重新创建的示例:

任何帮助将不胜感激，我真的是一个 javascript 菜鸟。

所以我只需删除示例的 CSV 部分就可以解决这个问题。这是链接到本地 d3.v3.js 文件的静态版本:
