javascript-d3How can I use d3.js to create a visualization in Qiita?

Qiita is a popular Japanese technical blog and online community for developers. You can use d3.js to create visualizations for your blog posts or articles on Qiita. Here is an example of how to do this:

// Create a SVG element
var svg = d3.select("body")
            .append("svg")
            .attr("width", 500)
            .attr("height", 500);

// Create a circle
svg.append("circle")
   .attr("cx", 250)
   .attr("cy", 250)
   .attr("r", 100)
   .style("fill", "red");

The above code will create a SVG element with a 500px by 500px size, and a circle with a radius of 100px and a red fill color.
