How to load svg files with d3?

@larissa 

To load SVG files with D3, you can follow these steps:

1. Include the D3 library in your HTML file using a script tag:

1

<script src="https://d3js.org/d3.v7.min.js"></script>

1. Create a container in your HTML where you want to display the SVG content:

1

<div id="svg-container"></div>

1. Create a JavaScript file and load the SVG file using the d3.xml() method. In this example, we assume the SVG file is named image.svg:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13

d3.xml("image.svg")
  .then(function(data) {
    // Once the SVG file is loaded, extract the document element
    var svg = data.documentElement;

    // Append the SVG element to the container in your HTML
    d3.select("#svg-container")
      .node()
      .append(svg);
  })
  .catch(function(error) {
    console.log(error);
  });

1. Style and modify the loaded SVG as needed using D3 and CSS.

This example demonstrates how to load an SVG file and append it to a container element on your HTML page. You can then manipulate or animate the SVG elements using D3 methods and functions.
