Interacting with Gadfly using the plot function

The plot function is used to interact with the Gadfly package and create the desired visualizations. Aesthetics are mapped to the plot geometry and are used to specify how the plot function would work. They are specially named variables. The plot elements can be scales, coordinates, guides, and geometries. It is defined in the grammar of graphics to avoid special cases, and aesthetics help this by approaching the problem with well-defined inputs and outputs, which produces desired results.

A plot can operate on the following data sources:

• Functions and expressions
• Arrays and collections
• DataFrames

Here is a simple example of a graph made using the plot function. We will be using IJulia to ...
