Clustered Heatmap Alt-Text (Example)

This clustered heatmap visualizes how frequently actors appear in different movie genres. Similar patterns are grouped together.

  • Julia Roberts and Tom Hanks show similar patterns, focusing primarily on Drama and Comedy
  • Jennifer Lawrence and Leonardo DiCaprio share a strong emphasis on Drama
  • Dwayne Johnson is an outlier in this dataset, with a strong specialization in Action and no Romance films

The visualization combines a data table (heatmap) with tree-like diagrams (dendrograms) on its sides that show how similar rows and columns are.

The heatmap displays five actors (rows):

  • Dwayne Johnson
  • Julia Roberts
  • Tom Hanks
  • Jennifer Lawrence
  • Leonardo DiCaprio

And four movie genres (columns):

  • Action
  • Drama
  • Comedy
  • Romance

Each cell indicates the number of movies an actor has performed in for each genre using color saturation. Dark cells indicate many movies. The rows and columns are clustered based on similarity patterns. The most similar clusters of actors and genres are connected with the tree above and to the left of the matrix.
