The Ultimate Guide to Choosing the Best JavaScript Charting Library

Charting libraries are in great demand, and their creation and use are becoming increasingly popular in languages such as JavaScript. As evidence, several JavaScript charting libraries are available, both commercial and open-source, with a wide range of functionalities to meet the demands of users.

But how can a developer make an informed decision and choose the best JavaScript charting library? It's a difficult question, but we're here to assist!

We created a comprehensive guide on JavaScript charts to help you learn more about them and the best JavaScript charting library. Without further ado, let’s jump right in!


What are JavaScript charts?

A charting library becomes necessary when examining a huge number of data points is deemed advantageous for an organization, a purpose, or a goal. The primary goal of data visualization is to aid various stakeholders in developing insights and comprehending their data, which will ultimately be translated into valuable information. But when does JavaScript come into play when designing charts, and what exactly are JavaScript charts? Let's take a deeper look.

JavaScript charts are a blend of many chart styles, such as 2D (also known as XY charts) and 3D charts, line charts, bar charts, or polar charts that are easy to grasp (eliminating all of the complexity behind data analysis) while providing a highly visual interface that allows for smooth client-side interaction.

Currently, a more intricate, specific, yet still straightforward option for data visualization is JavaScript charts. Every charting library must have client-side interactive capabilities in order to be regarded as a top-tier JavaScript solution for demanding and data-driven industries. The power of visualizing data depends on more than just critical factors like from where the data is accessed or the amount of data processing.


Why use JavaScript charts?

Data visualization and charts help us grasp data more quickly and easily. They can mean the difference between a good report and a great one. Charts are also utilized in presentations and real-time monitoring.

JavaScript charts are especially useful since they can be embedded directly on any webpage and serve the same audience as any other online content. JavaScript charts are often not limited by the client device and can be used on PCs, laptops, mobile devices, and tablets. Some modern solutions bring web applications almost everywhere, even outside of the web browser in desktop applications, mobile applications, and IoT devices.

Even if your application is not web-based, using JavaScript charts can be a good idea. Many contemporary desktop frameworks have some means to embed a website that you can use to obtain web charts in your desktop program. Because there are many possibilities in the online charts market, you will have a greater selection of available chart tools to pick from. Having the chart logic within a web control might also be advantageous since it can be exported outside of the main project and utilized as a separate feature.

JavaScript charts are constantly changing and being streamlined, addressing the long-standing issue of speed limits in online applications. JavaScript charts now speed up data visualization using client hardware, allowing for the presentation of massive data sets and real-time data sources.


How to choose the right JavaScript charting library

Every choice in the selection of a JS chart library is extremely personalized and influenced by various factors. We'll discuss some aspects to consider when picking a charting library.

Several JavaScript charting libraries are available nowadays, but which ones are the best to use? Numerous factors, such as business constraints, the type of data, the purpose of the chart itself, and many more, influence this.

  • Is the library compatible with a large variety of chart types?
  • Is the library supported by your browser and UI framework?
  • What is the size of the data set?
  • Is the app intended for usage on the web, mobile, or both?
  • What browsers support a certain library? To find out, look at your browser's market share.
  • Do the library offer style and customization?
  • What JavaScript framework do you employ?
