I think it's showing how much those things are being used. For example, JAVA is being used 7.7% out of the total amount. The total amount is all of the percents added so : 30.8+30.8+15.4+7.7+7.7+7.7=100.1. About 100. JAVA is 7.7 out of 100. JS is 30.8 out of 100. CSS is 15.4 out of 100. The others the same way
I hoped I helped!
Nervous System
Skeletal System
Muscular System.
The Nervous System fires electrical signals to your muscles, galvanizing them into action and making them move. The Skeletal System helps to support the Muscular System and move blood throughout your body so your body can receive oxygen. Your Muscular System in turn keeps your heart beating and helps you with locomotion.
