How do I use d3.js to create visualizations?

// plain

D3.js is a JavaScript library used to create interactive data visualizations for the web. It uses HTML, CSS, and SVG to create visualizations.

To use D3.js to create visualizations, you need to include the D3 library in your HTML file.

<script src="https://d3js.org/d3.v5.min.js"></script>

Next, you need to select the elements you want to visualize.

var svg = d3.select("body")
    .append("svg")
    .attr("width", 500)
    .attr("height", 500);

Then, you can bind data to the elements and use the D3 functions to create the visualization.

svg.selectAll("rect")
    .data([10, 20, 30, 40, 50])
    .enter()
    .append("rect")
    .attr("x", 10)
    .attr("y", function(d, i) {
        return i * 25;
    })
    .attr("width", function(d) {
        return d * 10;
    })
    .attr("height", 20)
    .attr("fill", "green");

This code will create five rectangles with widths of 10, 20, 30, 40, and 50 pixels respectively.
