Data visualization

Data visualization has enabled us to make sense of large and complex data sets. From a corporate perspective this is great as it enables us to save time, money, improve efficiency and in turn increase profits.

Teachers use word clouds to help kids make sense of words, web designers add this to make websites interesting.

Here are some data visualization tools that I have come across that are interesting.

Ushahidi, which means “testimony” in Swahili, is a website that was initially developed to map reports of violence in Kenya after the post-election fallout at the beginning of 2008. Ushahidi’s roots are in the collaboration of Kenyan citizen journalists during a time of crisis. The website was used to map incidents of violence and peace efforts throughout the country based on reports submitted via the web and mobile phone. It is now used to visualize information.

Here is a list of other data visualization tools.

Many Eyes is from IBM/Cognos, you can upload a data set and it creates a visualization based on your settings e.g. graphs, word clouds

Here is an interesting representation of oil consumption by country.

Woordle is a great tool for depicting word clouds from text. I have used this to help me make sense of the content on my website.

Here are a few more tools that I came across.

Tagul – Tagul is designed for web masters who want to place nice clouds on their web pages.

Tagxedo – visually stunning tag cloud

Orange – Open source data visualization and analysis

Ggobi – open source visualization program for exploring high-dimensional data.

Have you used any of these tools? How have you used them or how could they be used?
