In this presentaion, we will use plotly to plot a simple interative graph using mtcars dataset.
I will plot horsepower vs miles per gallon and factored by cylinder.

Plot

plot_ly(mtcars, x = mtcars$hp, y=mtcars$mpg, mode="markers", 
         type="scatter",color=as.factor(mtcars$cyl), size=mtcars$disp )
