Evaluatie
State-of-the-art
6
• controlled experiment comparing design elements • widgets, mapping to graphic
• usability evaluation • controlled experiments comparing several tools • case studies • least common • natural environment • real tasks • time consuming • difficult to replicate and generalize
• also: re-design C. Plaisant. The challenge of information visualization evaluation. In Proceedings of AVI04: working conference on Advanced visual interfaces, pages 109–116. ACM, 2004.

Paper
• aim + target audience
• related work
• data set: origin, characteristics
• visualisatie & interaction + rationale
• technology & code reuse
• lessons learned & conclusion
Structuur
Beschrijf niet enkel de visualisatie, maar leg vooral uit waarom je die visualisatie zo gemaakt hebt:
• welke alternatieven heb je overwogen?
• waarom heb je die eventueel niet weerhouden?
• Hoe is het ontwerp geëvolueerd? Waarom?
• Enz.
dataset- origin - distribution of values - missing or erroneous values - size - API - …
code you’ve re-used:
mention in acknowledgements
or explain in technology section
Technology section
- data collection
- data processing
- d3 experiences
- code from elsewhere
Related work
- not just same data
- not just web pages
- scientific papers do exist!
- how is your work similar and different? why?
- Max 1 page (screenshots included) !
Suggested Exercise-per-team;
Scholar session: find 5-15 relevant papers…
- what did you search on?
- what did you find?
- why or how is this relevant?
See what you can find in 15 to 30 minutes ;)
Ook nog…
• geen chronologisch verhaal!
• als je problemen hebt opgelost, geef dan concrete voorbeelden!
• niet: ‘to prevent giving a false impression to the user’
• […]: kan je niet zo maar beweren
• page limit: 8 pages, including everything!
• Onderbouw nodig!
• “However while most people know the two World Wars that happened, they don’t know a lot about conflicts that happened later or those that were shorter in time”
is dat wel zo…
• Geen vage statements
• “The data speaks for itself and redundant non-data-ink was removed to keep the visualization clean and simple”

• Deadline: Zondag 5 juni 0u00! (insturen via email naar [email protected])
• Misschien later indienen bij workshop of conferentie…
• Afsluitend gesprek nodig tijdens examenperiode?
Finale demo
9 mei stipt om 16u
- 10+7 min/group
- tonen ipv vertellen
- rationale! (alternatieven…)
- demo
- lessons learned
