I am looking for an online tool that will create a line or bar chart that will be saved to a GIF format so it can become animated. I think I can do this in Excel but It would be faster for me if I used an online tool.
For example, I have a five year data series that I want to show as a animated gif showing the overall annual increase. e.g. the years are 2008 to 2012. the data is 80, 90, 100, 110, 120. I want to see the graph growing each year. This means I need to save a image file for each annual progression and then combine them into a GIF file. Then I want to post the GIF file to Twitpic and tweet it to my followers for them to digest and discuss. The GIF file will show the increase over and over again thus getting some attention to the issue I am illustrating. Thanks for your help!
