Thanks for the comments. I'll try to include all possibilities (using existing pChart or SVG) in my proposal. One more question, it was
required
on our part to submit a patch before we submit our proposal. I submitted a patch for mass table prefix change (
http://sourceforge.net/tracker/?func=detail&aid=3220779&group_id=230... ).
Its for one of the 'Tasks for Junior developers' and its working fine
(nijel
verified that) but not accepted yet, so will it count or I'll have to do something more before I could submit?
I changed the resolution to "accepted" and you don't need to send another patch before sending your project proposal.
Thanks
I had a doubt (it might be silly but I thought I should ask). One important feature of such a data visualization system is that it should not create confusion or represent something that the data is not. Consider the movie database example, when a user sees a plot of ratings vs year / genre vs lanuage, a lot of data points will overlap. So a lot of data will be hidden from the user at the first sight. What will a user make out of it? I know we handle such conditions by providing all the data instances when he clicks on the point but a user might not go that far. If he is not able to understand the initial plot he might not continue further ( like not zoom in/click data point). I am just a little concerned about the usability part and not the functionality.

I don't think that the plot contains all that. In the example I have seen, the X axis contained "year of release" and the Y axis was for "popularity level from 1 to 9".
There were buttons at the bottom to select genre but this was not part of the data points.

No I am saying that a lot of movies will have same year of release and same
popularity. Those movie points will overlap on the 2D space, what then?

One solution is to allow for adding random jitter to point coordinates in order to scatter them around their real position, like it's done for scatter plots in RapidMiner ([1], last screenshot).

Yes, probably or like collisions resolution in hashing. I'll think on it more. I've submitted my proposal, hoping to get some feedback. Is it okay if we concentrate more on a stable,usable product than implement many advanced functionality? Because here it seems to be the case where we can add a lot of statistics into the system.

Choosing what is basic functionality and what is advanced, is open to interpretation; a usability test with a group can tell you more.

I agree.
Also, in the proposal should we mention exact working of the zooming tool? I'm thinking that the functionality is fairly clear and many of available plugins could well be of use. So we can maybe use those (with modifications to our needs) instead of coding everything from scratch. It will also be good if the zooming tool is something like they have used earlier e.g. like google maps zooming. User might find such system more friendly.

I don't think that the proposal should go too deep into implementation details.

Sir, I was hoping if I could get some comments on my proposal once before the deadline. I had submitted mine on 2nd.
