1. Zaap Visualization of web traffic from http server logs

2. Target Users  Web Developers Identify problems Collect statistics on users browsers  Site owners Evaluate return on investment  Marketing departments Track traffic sources Evaluate ad campaigns View traffic trends

3. Tasks  View traffic patterns over time  Filter display by many variables Date Page Browser Entry page Error codes User statistics Purchasing behavior Referral page / Search terms

4. Data  Automatic web server logs analyzed to identify patterns.  Example: 71.197.130.31 - revitupracing [25/Apr/2006:10:33:42 -0500] "GET /stylesheet.css HTTP/1.1" 304 - "http://www.revitupracing.com" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1;.NET CLR 1.1.4322;.NET CLR 1.0.3705)"

5. Scenario of use  Joe Corp. just launched some new products on their website and they want to know how that launch is effecting the traffic that views their existing products.

6. Evaluation  Define detailed tasks  Create paper prototypes for those tasks  Observe users interacting with the paper prototype. Looking specifically for: Ease of use Accuracy User satisfactions Unforeseen applications that we might want to support

7. Risks  Because of the complexity of our data set we may not be able to base our paper prototypes on real data, we may have to simulate typical data instead.  Hypothermia

8. Design ideas  Graphical display of traffic over time. Bar graph or something similar  Filter the data with sliders bar grams based on the variables identified before.  Option to toggle display of traffic between different metrics Page views Bandwidth usage etc.
