Why study this course?

Why should you study D3.js? There are many advantages to studying D3.js compared to conventional data visualization tools. D3.js is a JavaScript library that focuses on data, and it is a comprehensive tool for data visualization. Visualizing data is essential, as the human brain quickly processes a massive amount of data in the form of graphs and charts. D3.js makes it easy to convey information to another person.

D3.js has several advantages over other conventional data visualization:

  • D3.js works with existing web technologies, i.e., HTML, CSS, and JavaScript.
  • D3.js is flexible.
  • D3.js is fast and lightweight as it works directly in the browser.
  • It allows code reusability.
  • It works well with large datasets.
  • It gives you complete control over visualization.
