What was the Virginia Plan and why was it controversial?

The Virginia Plan was a plan that proposed a government that would have three branches. The first branch was the legislature, which made the laws. The second branch was the executive branch and they enforced the laws. The third branch was the judiciary branch, which interpreted the laws. The Virginia plan said that the legislative branch would have two houses and the number of representatives in both would be based on population. It was controversial because smaller states had a smaller population so they didn't get as much representatives as states with larger populations.
