What is Data Visualization?

Data visualization is like a tool that helps us see patterns and trends in data by presenting it in a visual form such as graphs, charts, or maps. It’s like when you use a picture to explain a story, and in the same way, data visualization uses visuals to help us understand the story behind the data.

For example, if you want to know which country has the highest number of smartphone users, you can look at a bar graph that shows the number of smartphone users in different countries. The graph can quickly show you which country has the highest number of smartphone users, and how it compares to other countries.

Another example is a map that shows the distribution of customer orders from different states or countries. The map can help you see where customers are concentrated and how they are growing and shifting over time.

Data visualization is essential in today’s world because we have access to more data than ever before. It allows us to analyze complex information quickly and make informed decisions. By visualizing data, we can communicate insights and trends to others in a simple and effective way.
