I'm not quite sure about the real practical use of stream graph visualizations, but I admit that they look very nice. In the last week I experimented a little with stream graphs and created a tool which helps finding nice color scales for stream graphs. It allows to define ...
Here are my ideas for the next version of Piwik Maps. The map has altogether four views: world, continent[1. Some continents are divided into serveral regions for better zooming performance] and two new country views for provinces and cities. In both country views there is one active country. All other countries ...
After writing down my latest ideas for better Piwik visualizations, I just couldn't wait to see them in action. Since the Open Flash Chart library doesn't support multi-level pie charts I decided to create the visualization from scratch. The initial version (0.1) took me about two hours coding. In the ...

In this post I want to present two ideas for improvements to the current Piwik visualizations. Screen resolution stats The first idea is about improving the screen resolution charts. Here is an example for the current available visualizations in Piwik: The current charts ...
If you're using Piwik, the open source web analytics tool, then you probably already missed a map visualization of your visitors location, which is a standard feature of all major web analytics tools. As I really like the idea of ...
This is an AIR application I built for an assignment in the course Interactive Systems at the university. This video demonstrates all features like touch guestures and filtering. Since I don't own a touchscreen, this is only a "fake" touch video. I'd love to try this out on ...

In the last part I gave five improvements to the charts that are shown in the Wordpress.com Stats plugin. I ended with the weekly visits chart, so now I conclude with improvements for the monthly visits chart and presenting the idea of putting all the three into one chart.
Wordpress.com Stats is the most used statistic plugin for wordpress (with over 1.5 mio downloads so far). It offers a very simple way of collecting anonymous visit statistics and has a nice backend that lets you explore the data using line charts and tables. I keep using this plugin since the very beginning of this blog and I must admit that I'm looking at it every day. But in doing so I recently started getting bugged of the charts. This post series shows ten ways for improving them.
Today I want to introduce as3-proj, an actionscript port of the java map projection library by Jerry Huxtable, which is itself an partial port of the PROJ.4 library. It's basically a huge set of over sixty ...
I'm very proud to present my current visualization, which is my first serios step into the Processing framework. It shows some financial data of the world's biggest companies, tracked over the last 6 years. I took the data from Forbes2000-Index, which you can find on forbes.com.

There's some kind of hype around climate data these days. Since the UK’s National Weather Service recently published an enormous set of weather station data files there's a growing number of visualizations spreading the net. Among a few other examples I found this very nice and clear ...
View Visualization and interpretation of weather station data
The last days I worked on a visualization experiment that shows the geographic locations of blog page requests on a world map. Furthermore, the visualization should be animated over time, so one can replay past events or just view the current live data. The last thing I added was an ...
I just made a corrected version of the previosly mentioned visualization using ActionScript. I tried a few map projections and decided to use the Winkel III projection which has a few advantages over the Mercator projection. One of them is the accaptable area distortion of countries near the ...
Today I'm going to demonstrate a simple geospation visualization in flash. Therefore I used a scalable vector graphic of germany which contains individual shapes for every district. and labeled them to the specific district id used by lots of datasets. The common source for data about germany is the ...

In Anlehnung an das Einführungsbeispiel aus Ben Fry's schönem Buch Visualizing Data habe ich gerade eine kleine Visualisierung der deutschen Postleitzahlen gebastelt. Sobald der Flashfilm den Keyboardfokus hat, kann eine Postleitzahl eingegeben werden. Der zugehörige Bereich färbt sich rot. Als Datenquelle wurde die OpenGeoDB eingesetzt. Update: Mit der Taste ...
Easing-Funktionen werden verwendet, um sanftere Bewegungsabläufe in Tweens zu erzeugen[1. siehe auch http://www.robertpenner.com/easing/]. Die Funktionen berechnen in Abhängigkeit von der verstrichenen Zeit t, dem Startwert s, der gewünschten Wertänderung c und der Gesamtdauer der Animation d einen neuen Wert für den Ort eines Objektes. Natürlich können Easing-Funktionen auch für ...
Die folgenden Visualisierungen sollen die Farbräume HSV, HSI, HSL und HSB veranschaulichen.

Die Sättigung fällt von oben nach unten hin, Farbwert/Helligkeit/Intensität fallen hingegen von links nach rechts. Bei den Darstellungen handelt es sich um Flashfilme, ...
