Here are two data representations from the same Daily Telegraph article about shootings in schools in the USA.
Comments?

I like the first one. This is very clear and shows when incidents occurred. There seem to be several weeks where lots of incidents happened.
February was less incident-filled than January. (NB this graph was published 15 Feb.)
There are some confusing things: Was 15 Jan a school-day? There was an incident on a Saturday. What does 'incident' mean? On the black-cross days - were there 2 incidents or more than that.
In the second graph things seem completely backwards! Here a smaller bar means the mass-shootings were closer together, which doesn't seem obvious. Is there a better way to show this?
Does it matter that the groups of years are not the same size?
Lots to talk about here!
