Scatter matrix of numeric columns

You've investigated the new farmer's market data, and it's rather wide – with lots of columns of information for each market's row. Rather than painstakingly going through every combination of numeric columns and making a scatter plot to look at correlations, you decide to make a scatter matrix using the pandas built-in function.

Increasing the figure size with the figsize argument will help give the dense visualization some breathing room. Since there will be a lot of overlap for the points, decreasing the point opacity will help show the density of these overlaps.

Instructions

100 XP
  • Subset the columns of the markets DataFrame to numeric_columns so the scatter matrix only shows numeric non-binary columns.
  • Increase figure size to 15 by 10 to avoid crowding.
  • Reduce point opacity to 50% to show regions of overlap.
