我正在尝试在 React 中导入 D3v4 来生成 Dash 组件。到目前为止，这是我的代码：

import React, {Component} from 'react';
import PropTypes from 'prop-types';
import * as d3 from 'd3';

function createBox(divId) {
    var svgContainer = d3.select(divId).append('svg')
                                     .attr('width', 200)
                                     .attr('height', 200);

 //Draw the Circle
   svgContainer.append('circle')
                        .attr('cx', 30)
                        .attr('cy', 30)
                        .attr('r', 20);
}
