Top 10 Free Software for Data Visualization

The good news is that numerous free online data visualization tools can help you turn your data into meaningful and impactful visualizations. Whether you’re a business analyst, marketer, student, or someone interested in data, these free tools offer a wealth of options for creating high-quality visualizations.

In this article, we’ll explore the top free online data visualization tools, their features and limitations, and how you can use them to communicate your data insights effectively.

Free online data visualization tools often have limited features compared to paid ones and may have limitations on data storage and sharing options.

Paid data visualization tools typically offer more advanced visualization options, customizability, and technical support. However, the specific comparison will depend on the particular tools being compared. It’s essential to evaluate your specific needs and the capabilities of free and paid options before deciding.


The ease of use and sharing of visualizations created with free online tools can vary greatly depending on the tool. Some free tools have user-friendly interfaces and allow easy sharing through social media, email, or website embedding.

Others may have a steeper learning curve and limited sharing options. It’s essential to review the features and capabilities of the specific tool you are considering to determine its ease of use and sharing options.

When choosing and using free online data visualization tools, it’s essential to consider the following best practices:

Determine your needs

What type of data are you working with, what insights do you hope to gain, and what kind of visualization best suits your needs?

Research your options

Review the features and capabilities of different free online data visualization tools to determine which is best suited to your needs.

Evaluate the ease of use.

Consider the interface and overall user experience when choosing a tool. Make sure it is easy to use and understand.

Consider data limitations

Some free online data visualization tools limit the amount of data that can be processed and stored. Make sure the tool you choose can accommodate your data needs.

Check sharing options

Consider how you will share your visualizations, and ensure the tool you choose allows easy sharing through email, social media, or embedding in websites.

Keep it simple

Data visualization is most effective when it is simple and easy to understand. Avoid using too many colors, shapes, or text, and keep the focus on the data itself.

Continuously evaluate

As your needs change and the tool evolves, continuously evaluate it to ensure it still meets your needs and provides the insights you need.

Yes, free data visualization tools can deliver professional-looking results. Some popular free data visualization tools like Tableau Public, Google Charts, and D3.js offer a wide range of customization options, templates, and pre-built visualizations that you can modify to meet specific needs.

However, the functionality and data size limitations in free versions of these tools compared to paid versions may impact their ability to produce highly advanced and complex visualizations.

#1. Tableau Public

This is right at the top because it has all the beautiful features of the best online accessible data visualization tools. The company decided not to limit the features of the free version. Instead, this is the full version of Tableau that you can download for free, with one catch: everything you make with it is public, so it will automatically get posted on the web through Tableau’s visualization gallery.


The Tableau gallery is cool enough to be discussed independently since you don’t have to download or use the tool to enjoy it. Every visualization on this page can be downloaded and put into documents, emails, or web pages using code snippets that Tableau gives you.

Other people have done a lot of hard work on some unique ways to display data, and Tableau has gathered all of this content and made it available for download. This is a great resource not just for business people but also for researchers, students, and journalists who want to find ways to make their content more complete and attractive and keep it up to date.


#3. Microsoft Power BI

Microsoft Power BI, like Tableau, can be downloaded for free. Also, like Tableau, Microsoft has a visualization gallery that both Power BI users and people looking for free visualizations can use. Microsoft Power BI has impressive features and is undoubtedly one of the best free online data visualization tools.

#4. Google Data Studio

Google Data Studio is a part of the Google Marketing Platform that lets users build dashboards and multiple views of their data instead of just one visualization ready for publication.

Even though it has a learning curve, like most Google products, it’s not that hard to use. It also works well with Google Analytics, which can be a very powerful combination since you can use both tools for free.

#5. Openheatmap

This one says that you can turn your spreadsheet, which probably has some geographic data, into a working heat map with just one click.

It works with Google Spreadsheets, so if you want to use Openheatmap, you’ll need to import your Microsoft Excel spreadsheet there. But that’s a small requirement when you think about what could happen.

#6. Leaflet

This is not a tool for total beginners since it’s just a JavaScript library you’ll have to add to your data visualization framework. But it’s well-known because it’s minimal (only 33 KB) and does a great job of making maps and interactive maps for mobile devices.

Even for some of the paid BI tools we’ve looked at, that’s a tall order. So, check if you’re not afraid of the command line or calling an API (application programming interface). It is one of the best accessible online data visualization tools you should check out.


#7. Datawrapp

Datawrapper has backing from the company Datawrapper GmbH, based in Berlin, Germany. However, Datawrapper is international because a team of designers, developers, and journalists from the United States and several European countries built it.

The tool is for journalists who want to make quick, easy-to-understand visualizations to go with their articles. However, anyone who needs similar data views can use it. There is a paid version that helps the company, and there is also a free plan with a limit of 10,000 charts.

The tool is entirely web-based, and the website has instructions on how to use it, as well as an area called “Academy,” where you can take online classes to learn how to use Datawrapper. There is also an area called the River in the Gallery where users can share data and visualizations.

#8. Chartbuilder

This is a well-known tool for making charts publicly available by the financial news site Quartz in 2013. Quartz’s journalists made the tool to visualize numbers to make their stories stand out quickly. It is one of the best accessible online data visualization tools you should check out.

Even so, Chartbuilder could be more pretty and be the most accessible tool for rank beginners to use. To get the device to work, you’ll need to know how to download it and run a Python script. After that, it’s as easy as copying and pasting data into the tool, which isn’t pretty but is very simple. The device will then make a graphic that you can change using the tool or style sheets.

Aside from being a little hard to set up at first, the tool’s only downside is that it needs to make interactive visualizations like most other tools on this list do. Chartbuilder can only create static charts, but they are very polished, as they should be for a tool to take numbers and turn them into polished, published content in a few easy steps.


#9. Information is Beautiful

This is just a growing collection of exciting visualizations that other people have already made using various tools. The gallery is fun; you can download everything, but you need to read the licensing agreements first.

Individuals, especially students, and academics, have free access to these visualizations because of these agreements. However, if you want to use them for commercial work, you’ll have to pay some money. How much you pay depends on who you are and what you say in an email to the site’s owner. It is one of the best accessible online data visualization tools you should check out.


#10. Open Refine

Data transformation is a vital part of data visualization that we overlook. This is especially true now, when “big data” is trying to make sense of information from many different sources, like a spreadsheet or a long transaction log that a machine learning (ML) algorithm has found.

Most of the time, “transforming data” means taking a lot of different numbers and turning them into a smooth set of numbers that people can understand. That means cleaning the data (formatting and checking for errors), transforming it (changing it from one format, like native Microsoft Excel, to another, like XML), and then making it available to external services, like websites and BI tools you’re using.

If you think this can be a hard, time-consuming, and mind-boggling task, you’d be right… unless you use a tool like Open or Refine to change data. This tool used to be part of Google but was changed to stand independently. It’s still free and easy to use, so if you’re trying to make sense of a mountain of data that doesn’t match, give it a try.
