 The `ggplot2` package by *Hadley Wickham* follows a layer by layer plot building philosophy. In order to build a plot using `ggplot2` , the ideal way is to think in terms of plotting layers.
 
 **The steps involved in creating a plot are as follows:**
-
-  +**Step 1:** Add dataset:         `ggplot(data)`
-  +**Step 2:** Add geometry(layer): `geom_point(x,y)`
-  +**Step 3:** Add Plot title/change axes scales/faceting
