DistrictCluster（行政区划聚合）react中的使用

效果：

import React, { PureComponent, Fragment } from 'react';
import { connect } from 'dva';
import { Row, Col, Card, Form, Button, message, Cascader } from 'antd';
import styles from './Index.less';
import PageHeaderWrapper from '@/components/PageHeaderWrapper';
import { G2, Chart, Geom, Axis, Tooltip, Coord, Label, Legend, View, Guide, Shape, Facet, Util } from "bizcharts";

const FormItem = Form.Item;

/* eslint react/no-multi-comp:0 */
@connect(({ index, loading }) => ({
	index,
	loading: loading.models.index,
}))
@Form.create()
