Data visualization allows us to analyze and understand huge amounts of data at with ease. After all, it would be difficult to analyze surveys, polls, or simple data just by looking at single records. The advancement of technology now allows us to take either libraries or tools to help us give our data a more visual look.When I say libraries, I mean the collection you can find on sites like GitHub. There are a lot of cool data visualization libraries to choose from, but we’re going to take a look into broader tools.

As the amount of data that becomes readily available to us grows, more and more people are developing and using smart data analysis tools. Not only do they help spot patterns and interesting insights about the given data table, it also allows us to use the findings and publish them as blog posts, search papers, essays, etc.

So, without further ado, here are 10 amazing free tools that you can use for data visualization. Make sure to check out their features and see what works for you best.

Enjoy!
