What are Area Charts?

Area charts are data visualizations best used for showing cumulated totals using numbers or percentages over time. They are basically line charts that are filled in to provide a deeper view of multiple series of data.

Like traditional line charts, area charts are set against a common scale and are ideal for showing trends in data over time. You might also add a trend line or goal line to illustrate performance in a certain period against a set benchmark.

Area charts are one of many types of data visualizations used to organize and present data in a way the audience can understand and take action on. To ensure visualizations have real business value, it’s important to know which types of visualizations are best suited for a given data set.

The Significance of Area Charts in Data Analysis

Area charts serve as a critical component in the arsenal of data visualization techniques. They excel in illustrating how different components stack up against each other over time, making them indispensable for comparing multiple data series within a common scale.

Key Features of Area Charts:

  • Cumulative Totals Visualization: Perfect for showcasing how individual values contribute to a total over a period.
  • Trend Identification: With their ability to highlight fluctuations, area charts are ideal for spotting trends and changes in data over time.
