10 Free Visualization Tools You Can Use to Make Sense of Web Data

10 Free Visualization Tools You Can Use to Make Sense of Web Data

According to IBM, over 2.5 quintillion bytes of data are generated daily, with the number ever-increasing.

Now, let’s put this into perspective: one terabyte of data can be the equivalent of:

  • 17,000 hours of music
  • 1,000 hours of video
  • 310,000 photos
  • 500 hours of movies
  • About 86 million Microsoft Word documents
  • Over 132,000 650-page books

Now, take one of these terabytes and multiply it by 2.5 million. That’s how much data we produce in a single day. With this amount of data generated daily, making sense of it all can be overwhelming.

That’s where data visualization tools come in handy. These tools allow us to interpret and understand data visually, making it easier to identify patterns, trends, and anomalies.

So, What’s Data Visualization?

Data visualization is the process of taking a data set and transforming it into a visual representation, such as graphs, charts, maps, or infographics. This allows us to not only analyse large amounts of data quickly but also identify patterns and trends that may not be apparent in raw data.

Otherwise referred to as Data viz, data visualization is a powerful tool used by businesses, researchers, and analysts to communicate complex data in a simple and easy-to-understand format.

Data Visualization Tools

So, how do you create these data visuals?

There are tools specifically designed for this.

We’re not talking about Adobe Photoshop or Microsoft Excel here. We’re talking about specialized tools specifically designed for data visualization.

Adobe Photo, Illustrator, and Microsoft Excel can work, but they all suck at creating dynamic charts and graphs. And if you’re not a graphic designer, it’ll take you a lot of time and effort to create something presentable.

That’s where free data visualization tools come in to save the day.
