#data visualisation graphs

This is a great example of “data mining”, where you look for some pattern that fits the pattern that you’re seeing now, so that you can extrapolate to make some random prediction. 

And if you look at the two lines that have been stretched and overlaid to make it seem like they overlap, they haven’t even done a good job of that - it’s hard to see how the two lines are similar. 

Now leave the bad data aside and let’s stick to the visualisation - What’s with the background? The shadows of the lines? The overall UX?The selective axes labels (0-10-30-50 on the left) and so on.
