Data and information visualization is a way of looking at things in a visual and organized way. It helps us look at data or information in a way that we can understand and make decisions based on what we see. It's like making a picture or drawing out of numbers, data, and facts. For example, a bar chart might be used to show how different types of food people eat. The bars would represent the different types of food and the height of the bars would represent how much of each type of food is being eaten. This way, we can quickly see which types of food people eat the most and make decisions about what to cook more of.
