Turn messy, jumbled, and complex data into beautiful visualizations with data tools.

Data visualization software is an integral part of working in data whether you’re a data scientist or data analyst. By effectively visualizing data, you can draw meaningful insights, patterns, anomalies, outliers, and much more.

Additionally, datasets are often far too big to be able to draw insights from without aggregating and sorting data. Imagine trying to work with thousands, if not millions of data points. The brain cannot interpret such large amounts of information.

It helps that our eyes are drawn to colors and patterns.

Below are a few common ways to visualize data:

  • Charts (Gantt, area, bar)
  • Tables
  • Graphs (bar, line, wedge stack)
  • Maps (dot distribution, heat, tree)
  • Infographics
  • Dashboards

Below you'll find a selection of data visualization tools are used across the industry, and have varying levels of applicability depending on the data you work with, as well as the audience you want to educate.

Additionally, these tools have varying learning curves where some, like Tableau are no-code, while others, like D3.JS runs on JavaScript and uses HTML, CSS and SVG.

Top Data Visualization Tools

Data Visualization Tools


Tableau is an interactive data visualization tool that’s known for its ease of use and ability to drag and drop features into a dashboard.

Of particular note is the fact that Tableau can be used for mapping data from a multitude of sources (not just Excel) as it allows one plot latitude and longitude coordinates. Tableau is an excellent tool for anyone working with data, and can be particularly useful when trying to visualize and present data in a digestible way, with real-time changes.

Tableau is covered in our Intro to Data Analytics part-time course, and involves connecting a Microsoft Excel worksheet to visualize data. Overall, Tableau offers a wide range of functionality in terms of working with data sets from various sources and performing statistical analysis on them.

With Tableau, toggling between dashboards is also easy and intuitive. You can see a number of public datasets and dashboards in Tableau’s gallery here to give you a sense of what’s possible.
