I have created an excel spreadsheet that pulls data from the web, it works great. The only problem is that I can't tell if the data has changed over time. The website that I am pulling from doesn't track changes over time but it would be helpful for me. Is there a way to graph the data over time?

Is there a finance website that can plot historical and current graphs of a stock price in a currency other than that of its local exchange, e.g. the stock price of IBM in USD multiplied by the (moving, not current!) EUR:USD exchange rate? If this is easy to do on Google or Yahoo Finance then I'm obviously missing something!
I need help putting some data in a pleasing graphical form. In short, it is a history of a particular industry, with all of the companies, their founders and where they came from. I would like to build some sort of corporate family tree like this famous one. Does anyone know any good tools for this?

Math/CS majors: What algorithms are out there to do "approximate reductions for weighted graphs"? This is a term I made up, but basically I have a 200,000 node graph with weighted edges and I want to reduce it so I can see clusters and/or patterns. I know of SUBDUE, but it only works for unweighted graphs.
I need help graphically representing some data. [more inside]
Have you seen this trend/pattern/graph? The trend I'm looking for looks like a "checkmark". The x-axis is time. The y-axis can be related to rating/score/likeability/satisfaction (even toss me some goofy ideas). [more inside]
What is a good algorithm for generating smooth curves from discrete points? [more inside]
What's a creative way to graphically visualize user-rating vs time, taking # of ratings into account? [more inside]
I'm trying to track down a graph I once saw in a book - pretty sure it was an evolutionary psychology book - that compared the ratio of number of mates/sexual partners with either brain or body size among primates. Humans fell somewhere in the middle, at about 2.5 mates each (i.e. an argument about how "natural" monogamy is to our species.) Any ideas?
I have a 10 FPS video, and a set of numerical data for every frame in the video. How can I pair up each frame with its set of data in MATLAB?

Let's say I want to make a chart that's like an excel bubble chart, but I don't want the size of the bubble to vary depending on a third variable. Instead, I want the width of each bubble to vary by some amount, and the height of each bubble to vary by a different amount. [more inside]

How can I better present my information than a bar graph with both very tall and very small bars? [more inside]
Say I have 5 points: a,b,c,d,e. I know the position of each one at t=0: pa0,pb0 etc. Now say that at t=1, the distance between each one changes, so I know Dab1,Dac1...Dde1. Is there an equation or algorithm which will allow me to know (or aproximate) the positions at t=1 : pa1...pe1? [more inside]
Graph theory seems hot right now. Don't know much about it, though. If one wanted to learn some of the most practical, useable, and interesting results from the field where would one turn? Bonus points for applicability in social sciences and/or web apps. And, tangentially, if one was potentially interested in focusing on graph theory and the social sciences, where would one look at grad school? [more inside]
