An Area Chart is a type of data visualization that displays quantitative values over time or categories. It is similar to a line chart, but the area below the line is filled with color or shading, making it easier to see the volume of data. Area charts are useful for showing trends and comparing different data series. These charts can represent one or more data sets, allowing viewers to understand how values change over time. They are commonly used in fields like finance, marketing, and project management to illustrate changes in metrics such as sales, revenue, or website traffic.
