## What visual aids should I make to bring to a jury trial, and how?

I am going to have a day in court. There is an amount of relatively simple 2-dimensional data central to my case, that tracks the course two variable quantities over 9 years. I want the jury members to understand this data as easily and as well as can be. I'm guessing a few colored charts with x=time and y=the quantities would be a good way to accomplish this. But what exactly should I prepare to a accomplish this, in terms of size and layout? And what free software tools should I use to do it? [more inside]

## HWÆT WORLD: how should I generate and display graphs of prime numbers?

I haven't programmed much for years. Now I want to play around with different ways of visualising the Ulam Spiral and I'd like suggestions for the right tools to use. I want to generate or load arrays of (say) 100,000 numbers, depict them on a 2- or 3-d graph, and move the lighting and/or viewing angle to give an impression of depth. Details inside. [more inside]

## Fano Plane and Hexagonal Tiling - a deep connection or a shallow one?

I've been chewing on the Fano plane a lot these last few weeks, and have just noticed something that seems really interesting to me. Notably, that the seven lines of the plane map very nicely to the 7-color hexagonal tiling. [more inside]

## Measure how noisily I sleep :-)

I have a pretty bad case of night terrors. I am turning to the hive mind to help me identify a cheap and effective solution/device that will record the times when I'm audible throughout the night. I don't want to know what I'm saying as it sometimes freaks me out (nothing scary, I'm just weirded out by listening to myself yell/whisper subconciously). So a tape/voice recorder is out of the running.
In short, I need to know what time I make noise, and maybe a little squiggle or number on a piece of paper/read out screen letting me know how loud I was relative to the rest of that night (I'm thinking of the needle that scrbbles on rolling paper with a time stamp next to it like a seizmograph).
Any suggestions? This can be hand made or purchased as long as it's not too expensive :-)

## "Bars that get shorter over time"?

In the Sims games, each Sim has a set of bars representing their needs that get shorter over time. Each bar gets shorter and shorter until the need (e.g., hunger) is met. I can imagine the same kind of bar graph being used for a gas gauge or a visual representation of a bank balance. Does that kind of graph/gauge have a name?

Please help me make more meaningful graphs for my boss! Our department runs computer labs on campus, and being the end of the school year we're looking at utilization rates.

But none of us can really figure out what formula to use. [more inside]

## A question about graphs

On

__blank__graph paper, what is the mathematically proper name for any random line you see on the page? It wouldn't be "coordinate" since that refers to the line's value. It wouldn't be "grid" since that refers to all of the visible lines. It wouldn't be "axis" since there can be only one in each direction. I'd also be cool with the name for all of the lines (as a set) that are parallel to one another. Thanks!## Software for making clever information visualizations?
