Let us look at the complete code and the resulting plot: The code above will yield the following output: While this is a good start, it is not very nice to look at yet. Seaborn is the closest thing there is, but it just does not have the flexibility of ggplot (e.g. You provide the data, tell ggplot2 how to map variables to aesthetics, what graphical primitives to use, and it takes care of the details. However, if you are a frequent user of Python, then implementing the grammar of graphics can be extremely challenging due to the lack of standardized syntax in popular plotting libraries, such as matplotlib or seaborn. # R ggplot (data = poke) + geom_point (mapping = aes (x=Attack, y=Defense, color=Legendary))+ scale_color_manual (values = c ('#F85C54','#2ACC74'), The grammar allows users to compose plots by explicitly mapping data to the visual objects that make up the plot. python ggplot2 python-ggplot.
