If you want to learn about data visualization, it’s important to know about line charts and column charts.
A line chart is a type of graph that displays information as a series of data points connected by straight lines. It is mainly used to show trends over time. Each point on the line represents a value at a specific time, making it easy to see how something has changed. For example, a line chart can show how a company's sales grow each month.
A column chart is another type of graph that uses vertical bars to represent data. Each bar stands for a category and the height of the bar shows its value. Column charts are excellent for comparing different groups. For instance, if you wanted to compare sales of different products, a column chart would help you see which product sold the most.
Using line charts and column charts makes it easier to understand data. These visuals help people make decisions based on trends, comparisons, and clear information. For example, if you’re analyzing sales performance, these charts can help you quickly identify areas that need improvement.
