Oil spills

Hello Michael,

I'll be happy to help you out. Here is my opinion:

01. As you acknowledge it, the average user does not know what kernel density estimation is. I would say that the vast majority of Wikipedia users have never even heard of it. What use would be a graph which nobody can understand? Very limited indeed. You'd rather just make a regular line chart (I prefer them over bar charts) showing the spills per year.

02. Your graph had no sources. You should add them.

03. It's very easy to add an explanation and control the size of the image. Just click on edit and check out what I did to edit your image:

If you have more questions, don't hesitate to write me. Cheers. --Evenfiel (talk) 08:56, 3 June 2010 (UTC)

The chart does make sense, it's called a kernel density estimation and it represents the frequency of incidents per year (1 every 5 years would be 0.2 incidents/year). You'll see that there has been a gradual increase over the past 50 years, with a few surges.
