There are two common ways to represent data visually in computer applications: charts and graphs. Both charts and graphs can be used to show trends, patterns, and relationships between pieces of data. The type of data representation you choose will depend on the type of data you have, as well as what you want to communicate with your audience.
Charts are best used to compare data points or categories. For example, you might use a bar chart to compare the sales of your company's products in different regions. Bar charts are also useful for showing trends over time, such as monthly sales figures.
Graphs are best used to show relationships between data points. For example, you might use a line graph to show the relationship between temperature and ice cream sales. Line graphs are also useful for showing trends over time, such as the rise and fall of the stock market.
