π Topic Summary
Data visualization is all about representing information (data) in a visual format, like charts, graphs, and maps. In computer science, it helps us understand patterns and trends that might be hard to see otherwise. For Grade 5, we'll focus on simple ways to visualize data using tools you might already know, like spreadsheets or drawing apps. By visualizing data, we can easily compare different sets of information and make better decisions. It's like turning detective, but with pictures!
