This line graph represents how much wast was produced by three factories between 2000 and 2015.

The line chart illustrates the quantity of

produced by the three companies, namely A,

B

, and

C

over the span of 15 years from 2000 to 2015.

.

By contrast

, starting at over 4

tonnes

, the quantity of garbage

company
