I'm sure that there were some statistics involved here...

Assume that you are a newspaper reporter and you have been tasked with constructing a graph that depicts data showing that increased smoking causes an increased risk of lung cancer. Given that people might be helped and lives might be saved by creating a graph that exaggerates the risk of lung cancer, is it ethical to construct such a graph?
