Zoom Search (and more AJAX) I'm not sure if anyone has ever looked into it, but jqPlot looks like it'd be ideal for this. It already has a zoom feature, offers a bit of "shininess", and would be quite straight forward to implement, I feel. Since pma is already implementing jQuery, using a plugin of it makes sense. jqPlot also offers a simple line of best fit. Would a few more simple mathematical functions (K-means, standard deviation, Cov?) be worth it? While I don't expect anyone to want to do anything serious in a browser, it might be worth it to have a simple way of viewing trends without having to export the database to something like matlab.
It's very unlikely you will be able to do anything useful with clustering that way, unless you extend it to more than two variables and generate group descriptions. Analysis in two dimensions can be done by simply looking at charted variables, automatic analysis is useful if you want multivariate analysis which can't be done easily that way.
Personally, I would steer away from any advanced statistical analysis - just concentrate on solid visualization of data.
