Graph drawing is an area of mathematics and computer science combining methods from geometric graph theory and information visualization to derive two-dimensional depictions of graphs arising from applications such as social network analysis, cartography, and bioinformatics.
A drawing of a graph or network diagram is a pictorial representation of the vertices and edges of a graph. This drawing should not be confused with the graph itself: very different layouts can correspond to the same graph. In the abstract, all that matters is which pairs vertices are connected by edges. In the concrete, however, the arrangement of these vertices and edges within a drawing affects its understandability, usability, fabrication cost, and aesthetics. The problem gets worse, if the graph changes over time by adding and deleting edges (dynamic graph drawing) and the goal is to preserve the user's mental map.
Graphs are frequently drawn as node-link diagrams in which the vertices are represented as disks or boxes and the edges are represented as line segments, polylines, or curves in the Euclidean plane.
Drew Blyth Barrymore (born February 22, 1975) is an American actress, film director, screenwriter, producer and model. She is a member of the Barrymore family of American actors and granddaughter of John Barrymore. She first appeared in an advertisement when she was 11 months old. Barrymore made her film debut in Altered States in 1980. Afterwards, she starred in her breakout role in E.T. the Extra-Terrestrial. She quickly became one of Hollywood's most recognized child actresses, going on to establish herself in mainly comic roles.
Following a turbulent childhood which was marked by drug and alcohol abuse and two stints in rehab, Barrymore wrote the 1990 autobiography, Little Girl Lost. She successfully made the transition from child star to adult actress with a number of films including Poison Ivy, Bad Girls, Boys on the Side, and Everyone Says I Love You. Subsequently, she established herself in romantic comedies such as The Wedding Singer and 50 First Dates.
In 1995, she and business partner Nancy Juvonen formed the production company Flower Films, with its first production the 1999 Barrymore film Never Been Kissed. Flower Films has gone on to produce the Barrymore vehicle films Charlie's Angels, 50 First Dates, and Music and Lyrics, as well as the cult film Donnie Darko. Barrymore's more recent projects include He's Just Not That into You, Beverly Hills Chihuahua, Everybody's Fine and Going the Distance. A recipient of a star on the Hollywood Walk of Fame, Barrymore appeared on the cover of the 2007 People magazine's 100 Most Beautiful issue.
