Wondermaths - 9 - Graphs

80s edutainment at its best! Wondermaths was a schools programme dressed up in a space story about Zak, Stella, and their irritating robot Hudson (all from the planet Theta) trying to get to Earth for a holiday. On the way they encounter various life-threatening space phenomena that can only be defeated by the power of maths.
This episode talks about graphs and charts, in the context of an overheating problem.
