I want to embed some column charts into my articles. I don't have Excel or Power Point or Photoshop.

I've looked through this list (Picktochart, Infogr.am, Google Chart, DIY Chart, etc.) but am not sure which one I will be able to use. Ideally, the chart should come out as an image. I'm basically looking for a tool with pre-made chart, where I can put my data in and that's it. Mostly they will be charts, like 10 foods high in vitamin C and so.
