Radar chart is used to graphically represent differences between actual and ideal performance or to show different data in two-dimensional form chart of two or more measureable variables symbolized on the axes beginning from the same point.Â

Radar charts, also known as spider charts or web charts, are a unique and effective way to visualize multivariate data. They allow you to display data points on a circular grid, making it easy to compare multiple variables at a glance. To truly harness the power of radar charts, it’s essential to understand the underlying formulas and how they shape this distinctive data visualization. In this guide, we will delve into the formulae that bring radar charts to life and help you make the most of this visualization technique.

### Concept of Radar Chart :

• Data Structure: Radar charts represent data using a series of axes emanating from a central point, forming a polygon-like shape. Each axis corresponds to a different variable or category.

• Data Points: Data points are plotted along each axis, and their distance from the center indicates the value of the variable they represent.

• Connecting Lines: Lines connect the data points to create a closed shape. These lines, often referred to as “spider webs,” provide a visual representation of how each variable relates to others.

• Normalization: To ensure fair comparisons, it’s common to normalize the data by scaling all values within a consistent range (e.g., 0 to 1).
