Actually, you don't need any coding to create fantastic and interactive visualizations for the web. You can always use a charting service. There are many; some are paid, others are free. They offer configuration screens and data transformation tools that allow you to create all kinds of beautiful charts. Popular services include Google Charts, Tableau, Infogram, and Plotly. If they fully satisfy your data visualization needs, you don't really need this book.

But if you know HTML, CSS, and JavaScript, you don't need to use these platforms. Web standards provide all the tools you need to create any sophisticated graphics, with no restrictions imposed by a platform or a plan. Using web standards also facilitates the integration of your visualizations with web applications, frontend frameworks (such as React, Angular, and Vue) and backend web services (such as resources and data provided by RESTful services).

But do you really need to use a library like Chart.js? Can't you just use standard JavaScript, HTML, CSS, and Canvas?
