10 Open Source Data Visualization Tools in 2022

Data Visualization Tools

In data visualization tools, graphs, charts, tables, maps, and other precise graphics are used to portray information in a visually appealing manner.

When it comes to data-driven professions, they typically integrate data display and analysis to assist professionals in making more informed judgments (such as engineering, data science, and business analysis).

Choosing the most appropriate Data Visualization Tools will assist you in reducing data inaccuracies while also saving you a significant amount of time and resources in your workflow. Furthermore, opting for open-source choices would give you a great deal of flexibility in terms of modifying the tool in question to meet your specific requirements.

The Most Powerful Open-Source Data Visualization Tools Software Available


Cloud-based and free, Redash is a data visualization and analytics tool that can be used to look at data. On a SQL server, it can be used to write SQL code. The tool comes in both hosted and open-source/self-hosted forms. That’s not true, though. By November 30, 2021, the hosted version is going to be shut down.

Redash can be used in the following ways:

  • To make dashboards that show data.
  • To connect with a lot of different data sources, get information from them, and also smartly query them. As a bonus, it can also put all this information together in a single place so everyone on the team can quickly get their hands on it.
  • That reminds me that Redash can also be used to share data with team members and help them work together. Reports and visualizations can be shared in a variety of ways, such as by using URLs, web embeds, emails, and more, to spread them around.

I think Redash is one of the best open-source tools for data visualization and analytics because of the following:

  • It has a lot of different ways to show data. They include pie charts, bars, tables, and graphs like line graphs, pivots, cohorts, scatter graphs, maps, and many other types of charts and graphs. You can also use it for other purposes. You can set up alerts and get notifications on things that could be data sources.
  • Using Redash is easy because it has a simple SQL client and interface. Users can easily browse schema, make snippets, call up and insert queries, do a lot more, and more with these tools on their side, as well.
  • Being in the cloud, Redash can be used from anywhere there is an internet connection. It can be used from anywhere.
  • Redash has a lot of customization options because it is open source. You can even change its features from the code level if you have the skills.
  • Users can use pre-set key performance indicators to make reports.
  • Single sign-on and other security features make Redash one of the safest data visualization tools on the market, so it’s a good choice.
  • Redash has a lot of great features, but you can also use APIs to make it even better. This is how.


Charted is an open-source tool that lets you see data in a new way. It runs on the MIT license. It was first made by the blogging platform Medium.com.

I can say that the main feature of Charted is that it makes it easy to see data. To get data from a file, all you have to do is provide a link to that file. The system then shows you a complete set of data that is organized and easy to read.

charts are one of the best open-source tools for visualizing data. Here are some other reasons why:

  • Intuitive platform design. For example, the interface has only the most important features. Thus, it isn’t very weighed down. I also think this is because most of the work has already been done.
  • It shows the same results on any screen size.
  • It updates its charts often (at 30-minute intervals).
  • If you want to separate data series and charts, this is a great tool for that job.
  • Using Charted, you can also change the types, backgrounds, titles or labels, and more of the available data to make it easier to find what you want.
  • It can also handle a lot of different types of files. CSV, TSV, Dropbox share links, and Google Sheets are some of the file types that are included.

 Grafana Labs

Grafana Labs is an open-source Data Visualization Tools and analytics application licensed under the GNU General Public License 3.0. Besides being one of the best open-source options, I also think it’s a good choice for people who want to use data analytics to do their work.

This is why Grafana should be on this list:

  • Most of the time, the tool can help you get the information you need almost anywhere.
  • Once you have the data, you can use Grafana to see and query it with ease.
  • The tool has a lot of powerful collaboration features. Thus, you can use it to quickly make dashboards that are both dynamic and reusable. Once that is done, you can share the dashboards with your team.
  • For putting together data from different sources, Grafana is great. This feature, for example, lets you use the tool to show information from different sources on the same graph.
  • You can also use the tool to get live alerts from data sources. Its alert system also works with a lot of other things, like PagersDuty, Slack, and OpsGenie.
  • It makes it easy to keep track of your logs, and you can switch between metrics and logs with a lot of ease.
  • My favorite thing about Grafana is that it makes it easy to compare different results on a single screen. Because it is so easy to connect data, it almost feels like a walk in the park.


D3.js is an open-source JavaScript library that can be used to show and analyze data. D3.js is also known as D3. It stands for “data-driven documents,” and that’s what the letter D3 stands for. With a strong focus on web standards like HTML, SVG, and CSS, D3 focuses on data-based manipulation of documents that are quick and easy to work with, so

D3 is one of the top open-source data visualization tools available today for the following reasons:

  • It gives users the right to copy, use, modify, and distribute it. The only thing you need to do is say that D3 owns the copyright to the software wherever it is sold or given away. Users can even charge money to share the software. That’s because of a license that the Internet Systems Consortium gives out for free that lets people use the software that runs on the computer.
  • D3 is the most flexible game out there, and it’s better than any other game. It gives people the chance to get any kind of data and use it to change a document. To make an HTML table from a mess of data, for example, you can connect it to the system’s Document Object Model and use it to make a table (DOM).
  • JavaScript Object Notation (JSON), CSV, and geoJSON are some of the data formats it can read. JavaScript functions can also be written to allow D3 to read a wide range of other types of data, like XML.

RapidMiner is a cloud-based software suite. Every part of the suite is used to make sure that a sequential data analytics environment is safe. It’s merely one component.

Because RapidMiner is an open-source data visualization tool, I think it’s one of the best. They are here:

  • Easy to use. RapidMiner has an easy-to-use interface with drag and drops controls. Thus, you can use it to work with huge amounts of data without ever writing a line of code.
  • There are a lot of things that RapidMiner can do on its own. For example, it uses artificial intelligence, machine learning, and predictive models to do things in a database in a way that loops. This way, a lot of things get done without having to be done over and over again by humans.
  • RapidMiner, on the other hand, reduces data errors while saving a lot of time and resources.
  • RapidMiner’s interactive charts and graphs help you get to know your data set better through its charts and graphs. You can zoom in and out, pan, and more when you look at the results.
  • You can use RapidMiner to work with a lot of different types of data at the same time. The text, graphics, multimedia, and more are some of them. More than 40 of them.


If you want to make your web pages look nice and clean by adding charts and graphs, Chart, js is another service you can use.

Many other things make me think it is one of the best open-source data visualization tools out there as I write this now. They are here:

  • A few tools can mix data outputs, but this one is one of the few that can do that. It can, for example, show both bar charts and line graphs in the same thing. To make it easier to see how different parts of the same data set are, you can use this method.
  • Data outputs are shown in animated formats that make the information come to life. This includes things like transitions, effects, and so on.
  • You can change the way the data is shown to meet your needs.
  • The output is also based on the size of the screen.


RAWGraphs is built on D3.js, which makes getting and displaying data very simple. Here are some other things about this tool that make it one of the best open-source data visualization tools today:

  • It has a lot of ways to get and show data automatically. For example, you can put in comma-separated-values, tab-separated values, or just copy and paste from a spreadsheet into RAWGraphs and watch it turn into a beautiful picture.
  • It shows data in a variety of ways with different types of graphics. These are both traditional (like pie/bar charts and line graphs) and not-so-traditional ones.
  • For example, with RAWGraphs, you can look at the patterns and trends in your data set to learn more about it. The best way to do this is to map the different dimensions of your data set with the help of a visual variable.
  • You can save and change your work anywhere as vector or raster images.


Datawrapper is yet another open-source data visualization tool that I think is great. It’s free.

This tool has a lot of features and functions that make it easy to get data, show it, and analyze it. Some of them:

  • If you don’t want to sign up, you can use Datawrapper without having to.
  • Every person on the platform can make as many visualizations as they want.
  • The output is flexible and can be seen on any screen, even mobile screens.
  • You and your team can look at a visualization together and work on it at the same time.
