1 Find your purpose
Before you dive into data visualization, you need to have a clear idea of what you want to achieve with it. Are you trying to explore your data and discover patterns, trends, or outliers? Are you trying to analyze your data and test hypotheses, compare groups, or measure performance? Are you trying to communicate your data and tell a story, make a point, or persuade an audience? Depending on your purpose, you will need different types of data, tools, and techniques to create effective visualizations.

2 Learn the principles
Data visualization is not just about making pretty pictures. It is also about following some basic principles of design, cognition, and communication. You need to understand how to choose the right type of chart for your data, how to encode data with visual elements such as color, shape, and size, how to arrange and label your charts, and how to avoid common pitfalls and mistakes. You can learn these principles from books, blogs, podcasts, courses, or workshops on data visualization.

3 Explore the tools
There are many tools and platforms available for data visualization, ranging from simple to complex, from free to paid, from online to offline. You can use spreadsheets, presentation software, or online tools to create basic charts and graphs. You can use programming languages such as R or Python, or software such as Tableau or Power BI, to create more advanced and interactive visualizations. You can also use specialized tools such as D3.js, Mapbox, or Flourish to create custom and creative visualizations. You can explore these tools by reading reviews, watching tutorials, or trying them out yourself.

There are a variety and different tool you can use depending on your objective and domain. The most popular ones tend to be:- Tableau- Power Bi - Alteryx - Looker There are others, but all do relatively the same thing. Don't focus on all of them, just pick one or two to learn, and become efficient. You can use free resources like YouTube , or paid ones, like DataCamp and Udemy.

I believe it is useful to analyze the functionalities of new data visualization tools not as a continuous replacement for the tools currently used. Being able to switch from summary views to detail views to respond to the need for detailed information on specific topics, or to dynamically aggregate information based on the progress of the discussion on the analyses presented, requires a very different approach from the one-way communication normally used up to now, requiring the ability to tell data stories in an effective and personalized way.

4 Practice your skills
The best way to learn data visualization is to practice it. You can find data sets online, or use your own data, and try to create visualizations that suit your purpose and follow the principles. You can also join challenges, contests, or communities that encourage you to practice and improve your skills. For example, you can participate in Makeover Monday, a weekly project that invites you to create and share a better visualization based on a given data set and chart.

The first principle is to decide what story you wish to tell through these visualizations. And it shouldn't be dry numbers (X% of users like to do Y), but an actionable conclusion (We should migrate our users from Y to Z in order to increase profits). Then pick a tool and a layout that tells your story.

5 Seek feedback
Another way to learn data visualization is to seek feedback from others. You can ask for feedback from your peers, mentors, or experts in the field. You can also give feedback to others and learn from their work. You can seek feedback by joining online forums, groups, or networks that focus on data visualization. For example, you can join the Data Visualization Society, a global community that connects and supports data visualization professionals and enthusiasts.

Start by exploring online courses and tutorials on platforms like Coursera or Udemy. Additionally, consider reading books such as "The Visual Display of Quantitative Information" by Edward Tufte to understand foundational principles. Finally, engage with online communities like Reddit's r/dataisbeautiful and attend workshops or conferences to stay updated on the latest trends and techniques in data visualization. I've found that continuous learning and staying connected with industry peers are essential for mastering new skills like data visualization.
