A Sunburst Chart is a visual representation of hierarchical data, displaying relationships between different levels of categories. It consists of concentric circles, where each ring represents a level in the hierarchy. The innermost circle typically shows the top-level category, while outer rings break down into subcategories, making it easy to see how data is structured. This type of chart is useful for analyzing complex datasets, as it allows users to quickly identify patterns and proportions. Sunburst Charts are often used in data visualization tools and can effectively communicate information about categories like sales data, website traffic, or organizational structures.
