##### A spider chart is a graphical method of displaying multivariate data in the form of a two-dimensional chart of three or more quantitative variables represented on axes starting from the same point. The relative position and angle of the axes is typically uninformative.

- It consists of a sequence of equi-angular spokes, called radii, with each spoke representing one of the variables. The data length of a spoke is proportional to the magnitude of the variable for the data point relative to the maximum magnitude of the variable across all data points. A line is drawn connecting the data values for each spoke. This gives the plot a star-like appearance and the origin of the name of this plot.
- Spider charts are useful when you want to look at several different factors all related to one item. spider charts have multiple axes along which data can be plotted

##### Application

- The "spider chart" can be a format commonly used by management consultants to show their clients how an organization compares with those in similar companies.
- It also can be used as the control of quality improvement to display the performance metrics of any ongoing program.
- Furthermore, it is also being used in sports to chart players' strengths and weaknesses.
- For example, you could use a spider chart to compile data about a wide receiver on a professional football team. On one axis, you could plot the percentage of passes caught. Another axis would show his yards per completion; another, his completions per 100 plays; another, blocks made; and a final axis might show his interceptions So far as we can see, the spider has a broad application area.
