The data explosion in recent years has led to a corresponding need for businesses and organizations to communicate information in a way that’s accessible and engaging to different audiences. Visual content is becoming an increasingly popular means for sharing data.

Data visualization relies on visual representations like graphs or charts to convey raw data. Presenting data in a visual manner makes it easier to understand and faster to process, even for those who aren’t mathematically inclined or trained in analytics. Each visual data representation tells a story about the data, which can lead to more informed business decisions and favorable outcomes.

There are many different kinds of data visualizations, such as maps, histograms, scatter plots, and pie charts. Those who know how to present information in visually engaging stories have the power to help make sense of past events, provide insights on current trends, and offer predictions for the future.

What is a Data Visualization Library?

Data visualization libraries are designed to help users break down complicated ideas and create visualizations that depict this information. Choosing a data visualization library plays an important role when working with large or complicated datasets, as it can affect the kinds of insights taken from the data. There are many options to choose from, so it’s important to learn about the specific features of each to decide which library is best for your data visualization needs.

This article will explore ten of the most popular JavaScript libraries for data visualization in 2021.

What is JavaScript?

JavaScript is an object-oriented programming language that transforms static HTML websites into interactive sites. This language executes on the browser, and is able to update content, control multimedia, animate images, and validate form data. This dynamic language can be used to create games, design mobile, and web apps, and construct web servers. JavaScript is well-suited for data visualizations because of its ability to specify page behavior.

Benefits of using JavaScript for Data Visualization

Here are just a few of the useful features JavaScript offers for data visualization:

  • Interactive capabilities
  • Rich interfaces that feature drag-and-drop components
  • Because it is an interpreted language, it is quicker to use than other programming languages.
  • Regular updates
  • Prompt feedback to visitors
  • The versatility of use through Node.js servers

Drawbacks of Using JavaScript for Data Visualization

In addition to the benefits of using JavaScript, there are a few drawbacks to consider as well:

  • Unlike other programming languages, JavaScript does not have as many guides and how-to tutorials available. This means it may take users much longer to solve problems.
  • JavaScript has fewer data science packages compared to languages like Python and R.
  • Because JavaScript is interpreted differently in different browsers, code has to be run on different platforms before it can be published.
  • Since JavaScript code runs on the client-side, oversights and bugs are occasionally used for malicious purposes.

10 Best JavaScript Data Visualization Libraries

JavaScript is one of the most popular programming languages and has a variety of libraries that can be used for data visualization. Here are ten of the most popular JavaScript data visualization libraries in 2021:
