The dimensions of the d3 div remain constant despite any modifications to its attributes

In my angular application, I am trying to customize the width and height of div elements in d3 when I select a legend. Strangely, I am able to adjust the width and height of the svg element without any issues. Here is the issue illustrated:

Below is the current code snippet that I am working with:

  buildSvg() {
    this.host.html('').attr('class', 'host');

    this.svg = d3
      .select('.host')
      .append('svg')
      .attr('width', this.size[0])
      .attr('height', this.size[1])
      .attr('class', 'pie-chart')
      .append('g')
      .attr('transform', `translate(${this.size[0] / 2},${this.size[1] / 2})`)
      .attr('class', 'pie-content');

    this.legend = d3
      .select('.host')
      .append('div')
      .attr('class', 'legend');

    d3.select('.legend')
      .attr('width', this.size[0])
      .attr('height', this.size[1]);
  }

Answer №1

When it comes to Svg and html, there are some subtle differences between the two. Unlike svg elements, you cannot simply assign width/height to a div element in the same manner. The best approach is to set the style attribute with the appropriate CSS formatting. Check out the example below:

div.a {
 background-color: red;
}

div.b {
 background-color: green;
}
<div class="a" width="100" height="100">width="100" height="100</div>
<div class="b" style="width: 100px; height: 100px">style="width: 100px; height: 100px"</div>
