Testing of visualization projects

We develop small to large visualization projects for different tasks and industries and sometimes while rewriting them a couple of times in the process we hit walls because we discover that we need to add a lot of code to support new requirements. Now we have established a design process that seems to work well (at least we reduced the development time for each new project quite a bit), but we’re still left scratching our heads around this question: what exactly should we test when testing visualizations?

Hash Algorithm Randomness Visualization

I’m curious if anyone here has any idea how the images were generated as shown in this response: Which hashing algorithm is best for uniqueness and speed?

How to properly diagram lambda expressions or traversals through them in Architecture Explorer?

I’m exploring a piece of code in Architecture Explorer in Visual Studio 2010 to study the relations between methods. I noticed a strange behavior.

Building a Graph Editor – How to create a data driven graph

I am developing a graph-editor that uses drag and drop to build hierarchical graphs (containing nodes and links). Each node in the graph should be linked to a table in our database (SQL Server). I did a lot of research about libraries based on javascript or/and JSON specifications to draw nodes and links. There are a lot of great examples to follow, but I have no idea about the way I can link a graph to a database (SQL Server, Oracle, MySQL…). I thought about this architecture (Question posted on stackexchange.com)

Is there a better algorithm for visualising one-to-multiple aid flows in Gephy?

I’m using Gephy to create a social network analysis graph that of aid flows from donors to recipients. force atlas 2 bunches the nodes together, are there other settings to try so the graph would be more spread out and readable?
