When communicating data, charts and graphs are often more effective than raw data because they can visualize the relationships between different data points. This makes it easy for your audience to understand the information you are presenting and to see patterns that would be difficult to spot in raw data.
There are many different types of charts and graphs, so it is important to choose the one that best suits the data you are presenting and the message you want to communicate. For example, a line graph is a good choice for showing changes over time, while a bar graph might be a better choice for comparing different groups of data.
Using charts and graphs can also be a good way to make your data more visually appealing, which can help keep your audience engaged.
