Trying to use D3 with React to create a histogram

I am trying to make a simple bar chart using D3 in my web application that uses React for its frontend.

I'm new to D3 and I'm in a serious crisis to get the chart displayed on my webpage, so I figured the easiest thing for me would be to find a jsfiddle that displays a simple bar chart using D3 ( http: // jsfiddle .net / tommy351 / P4Z75 / ) and copy and paste the code into my dashboard.tsx file.

Note. The reason I chose D3 is because other, easier-to-use graphics libraries that integrate more seamlessly with React (like recharts, react-d3) don't have TypeScript definition files.

So here's a snippet of my dashboard.tsx file:

         import * as React from "react";
         import * as ReactDOM from "react-dom";
         import * as D3 from "d3";

         var data = [4, 5, 10, 16, 23, 35];
         var width = 500;
         var barHeight = 20;

         var x = d3.scale.linear()
             .domain([0, d3.max(data)])
             .range([0, width]);

        var chart = d3.select('#chart')
             .attr('width', width)
             .attr('height', barHeight * data.length);

        var bar = chart.selectAll('g')
            .data(data)
            .enter()
            .append('g')
            .attr('transform', function (d, i) {
              return 'translate(0,' + barHeight * i + ')';
             });

       bar.append('rect')
             .attr('width', x)
             .attr('height', barHeight - 1);

       bar.append('text')
              .attr('x', function (d) {
                return x(d) - 3;
               })
              .attr('y', barHeight / 2)
              .attr('dy', '.35em')
              .text(function (d) {
                return d;
               });
      render() {
         return ( <div>
            <svg id="chart"></svg>
            </div>
        );
    }
}

      

        
        
        
      

    

There are errors in my console:

I tried the same thing with several jsfiddles and got similar errors in my console and couldn't get the graphics to render. Any idea what the problem might be?
