We are also familiar that points are represented by dots.

If points are important in Geometry, they are also important for painters especially those who use the technique called pointillism. In pointillism, paintings are created meticulously using dots to form figures and sketches.  The painting above titled A Sunday Afternoon on the Island of La Grande Jatte (1884-1886) by Georges Seurat is an example of a painting where pointillism was used.
