That sort of thing is exactly what a heatmap is for. As to how to build one, think about a collection of points on the map laid out in a grid. Each point has a temperature associated with it; you then map each temperature value to a color, say with Red: 80 Orange: 70 and so on. That's your basic heatmap. Now, in the real world you don't generally ...

I'd say some of this relates to your corporate culture and the aspects of development that you need to measure most. No one can measure everything, so you have to find and monitor the sweet spots that are most likely to benefit your business. Here's a few I've found helpful at various times: Burndown charts - for Agile project especially - requires that ...

Personally I think the different kind of burn-down charts used in agile projects are incredibly powerful as they answer the basic question of "if the project continues to run as it has, when are we done?". In projects I usually use burn-downs for the current sprint and for the entire release. Estimates used to produce the release burn-down are of course less ...

UML is a great way to communicate design to technical resources on a project, though in my experience, the vast majority of non-technical project resources get lost with it. UML does indeed require a minimal level of training to fully understand it or formulate it. Some non-technical peers may be experts in Use Case diagrams lets say, but when they see a ...

Two simple things: only write functions that fit on one screen use a dual screen display (which is quite affordable nowadays) The last time I needed a "fanfold paper printout" of some code was for a legacy function with several hundreds LOC. After refactoring this monster into small functions I never missed fanfold printouts again.

To be successful in this task, I would proceed as follows: (1) Specify KPIs to be presented for each type of management level (I guess in your case, you will have 1) (2) Distill KPIs (e.g. LOC is to be avoided as indicated by bethlakshmi's post). Also, you need to ensure that the data reported is something you can produce or calculate accurately using the ...

A problem that may be related is one where I have program to show the changing process trees running on a computer, as a real-time animation. In that context each level of the tree generally goes from narrow to wide. So to keep regularity, you could keep larger subdivisions around for a little while before reducing them. For example. I have at the top ...

UML is probably the better-standardized and commonly used tool for this. Some of the diagrams and documents that can be generated in UML can be exceedingly large or complex when used to document bigger systems; however, some of them could be useful if you wish to reach a value/effort balance (i.e. document enough so that you have a good reference point ...

I like to use the white boards in my office and draw everything out, this allows for quick editing because you will forget stuff the first time around. White boards are not necessarily needed, you can use paper or whatever on your wall. Make sure to encapsulate all your objects/variables in a consistent unique shape (it helps later). You also do not need ...

D3 is a great library, whose pretty clever design is the result of many years of research. It is the descendant of Protovis, a library that was already very nice at its time. Then the author, Mike Bostock, moved on to something more dynamic (differences are outlined here). There is a fair amount of weirdness at first sight in D3. The ways you bind visual ...

From the comment by Ian in the answer Development tool is Delphi. i assume you mean the images though. For "linear" map i created a square bitmap of size nxn, (where n = Ceil(sqrt(hashTable.Capacity))). Rather than simply black for list entry is occupied and white for list entry is empty, i used an HSLtoRGB function, where the hue ranged from 0 ...

What are you "testing" for? Are you testing for accuracy of the visualization, in other words, whether the visualization matches the system it describes? In this case, consider a View Model: an object structure identical to the visualization. Write code that compares it to either (1) the view model to the system it describes or (2) a known correct ...

You could read through the excellent treatise The Grammar of Graphics, which elaborates on different properties of visualizations and how they convey or obstruct the flow of information to the observer. Although the book does not list a test plan for visualizations, it certainly brings to light to connection between code, model, media and perception. For me ...

Main Problem is a missing architecture What problem does your architecture solve? Even the most poorly designed application has an architecture, so unless you're starting from scratch, one exists. In your case, maybe no one bothered to document it. Management wants to know that you have one that gives the project some sort of advantage (e.g. ...

You might need to convert it to another format first. You could generate a graph of the grammar by using a combination of ANTLRWorks and GraphViz. Someone did something similar here to generate graphs for the Ruby, JavaScript, and Java 1.5 grammars.

Regardless of how you present the information, if you're looking for changes, like from one month to the next, I sometimes do blink comparison. i.e. put last month's display and this month's display in exactly the same screen position, and then quickly alt-tab between them. Differences show up easily. If you want to be fancier, you could do ...
