I saw an infographic recently called Why is [state] so... and thought it would be interesting to do the same for programming languages. Unfortunately, there's no convenient visualization (like a map) for programming languages, so screen shots will have to do. Here are a few results for the languages that Google actually recognizes as programming languages.
ASP.NET

C++

C#

Cobol

Erlang

Fortran

Haskell

Java

JavaScript

Lisp

Objective-C

Perl

PHP

Python

Ruby

Smalltalk

VB.NET

As a long-time Java programmer, I'm just pleasantly surprised that "popular" was the top result instead of "slow."
