To create multiple squares in d3.js, you can follow these steps:

  1. Include d3.js library in your HTML file:
1
<script src="https://d3js.org/d3.v7.min.js"></script>


  1. Create an SVG element to contain the squares:
1
<svg width="500" height="500"></svg>


  1. Write the JavaScript code to create multiple squares using d3.js:

// Define the dataset (size and position of squares)
const dataset = [
  { x: 50, y: 50, size: 50 },
  { x: 150, y: 100, size: 70 },
  { x: 250, y: 150, size: 90 },
  { x: 350, y: 200, size: 110 }
];

// Create the SVG element
const svg = d3.select("svg");

// Bind the dataset to square elements
const squares = svg.selectAll("rect")
  .data(dataset)
  .enter()
  .append("rect");

// Set attributes for each square based on the dataset
squares
  .attr("x", d => d.x)
  .attr("y", d => d.y)
  .attr("width", d => d.size)
  .attr("height", d => d.size)
  .attr("fill", "blue");


  1. Customize the squares as needed by changing the dataset and attributes such as colors, sizes, positions, etc.


You should see multiple squares drawn on the SVG element with the specified sizes and positions based on the dataset provided.
