## 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]

## Help me convert this graph into a table.

I have a bitmap of a chart (in polar coordinates) that I would like to convert into a format that some plotting package can recognize, and then retrieve values from the chart at specific intervals. How do I do this? [more inside]

## Turning user input into pie (charts)

WordPressFilter: I'm looking for a plugin/widget/codesnippet that will allow me to create a graph using input from the user. [more inside]

## Math and Crime

I've been asked to teach a week at a summer university. Help me to design the most awesome computer science/discrete math course ever. [more inside]

## What kind of graph plot am I looking for?

I have a series of tables describing a set of data and their values for certain points in time. I want to create a multi-line chart from this data so I can see the growth curves. Is there a name for this kind of plot? It must be a solved problem and some tools to do this but I can't google for it if I don't know the name of what I want. [more inside]

## Join some of the dots, throw the rest away

Map geeks: can I generate a polygon shapefile from the outline of a large collection of points? There's more detail, of course. [more inside]

## Generating Bézier curves from discrete point sets

What is a good algorithm for generating smooth curves from discrete points? [more inside]

## Looking for books or resources on basic practical graph theory

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]
