+be saved as a stand-alone HTML file, embedded in R Markdown documents or in a
+Shiny app, and made available in the RStudio viewer pane.  Hover the mouse
+pointer over a cell to show details or drag a rectangle to zoom.  A heatmap is
+a popular graphical method for visualizing high-dimensional data, in which a
+table of numbers is encoded as a grid of colored cells.  The rows and columns
+of the matrix are ordered to highlight patterns and are often accompanied by
+dendrograms.")
