Creating gridded layouts

Regular grids of Bokeh plots can be generated with gridplot.

In this example, you're going to display four plots of fertility vs female literacy for four regions: Latin America, Africa, Asia and Europe.

Your job is to create a list-of-lists for the four Bokeh plots that have been provided to you as p1, p2, p3 and p4. The list-of-lists defines the row and column placement of each plot.

INSTRUCTIONS
100XP
Import gridplot from the bokeh.layouts module.
Create a list called row1 containing plots p1 and p2.
Create a list called row2 containing plots p3 and p4.
Create a gridplot using row1 and row2. You will have to pass in row1 and row2 in the form of a list.

# Import gridplot from bokeh.layouts
from bokeh.layouts import gridplot

# Create a list containing plots p1 and p2: row1
row1 = [p1,p2]

# Create a list containing plots p3 and p4: row2
row2 = [p3,p4]

# Create a gridplot using row1 and row2: layout
layout = gridplot([row1,row2])

# Specify the name of the output_file and show the result
output_file('grid.html')
show(layout)
