Introducing Firework

• What is Firework– A visualization of movie data that helps user

identify major trends based on year, country of production as well as genre of the movie

• What are visualized– Audience reception of a movie has two facets:• Popularity: How many people watch the movie• Rating: how good they think the movie is.

– Country, year, genre

Questions and User

• Who will be interested– Movie distributors trying to import movie in U.S.,

want to know the audiences’ appetites• What questions we try to answer– How the popularity and rating of movies differ from

one country to another?– How do genres within each country differ from one

another in terms of popularity and rating?– What is the average movie trend of a specific

country from 1961 to 2011?

Data Gathering & Processing

• Source: IMDB• Movies: from 1961 – 2011• Popularity: Average # of votes• Rating: Average individual rating• Country: Movie number top 50 (except US)• Genre: Combined IMDB genres

Evaluation

Evaluation

• User Test– From 12-14, Dec.– Recruited 10 users

• Scenario: a film distributor who wants to import movies from other countries to US

• 6 tasks

What works well

• Firework: intuitive transition between the overview perspective and fireworks

• Time slider: intuitive navigation

Findings

• Finding1: The current implementation for firework needs improvement– No labels for genre.– Assume dots are clickable. – Confused why the grey out dot is clickable– Hard to close the firework

Findings

• Finding2: Better labeling is needed for main view and trend view.– The meaning of the dot size.– The label and legend is not obvious.

Findings

• Finding3: Locating desired countries was not intuitive as we expected– The country filtered was not used frequently– Search function isn’t obvious

Future Work

• Comparison genres across countries– Allowing multiple fireworks

• Dot size & overlap– Zoom function

• Two views – cause mental effort to interpret the visualization

• Explore country/genre data point– The ability to see the movie list under each point
