  • Requires knowledge of JavaScript and web development.

Example:

// Sample D3.js code to create a simple bar chart
const data = [30, 86, 168, 281, 303, 365];

const width = 500;
const height = 300;

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

svg.selectAll("rect")
  .data(data)
  .enter()
  .append("rect")
  .attr("x", (d, i) => i * 70)
  .attr("y", d => height - d)
  .attr("width", 65)
  .attr("height", d => d)
  .attr("fill", "teal");

Tips:

  • Use D3.js for highly customized visualizations.
