Abstract. We initiate a new problem of automatic metro map layout. In general, a metro map consists of a set of lines which have intersections or overlaps. We define a set of aesthetic criteria for good metro map layouts and present a method to produce such layouts automatically. Our method uses a variation of the spring algorithm with a suitable preprocessing step. The experimental results with real world data sets show that our method produces good metro map layouts quickly.

This paper investigates an interactive approach where users can help a system to produce nice drawings of directed graphs by giving hints to graph drawing algorithms. Hints can be three kinds of operations: focus on a specific part of the drawing that needs improvement, insertion of layout constraints, and manual changes of the drawing. These hints help the system to escape from local minima, reduce the size of the solution space to be explored, and input domain knowledge. The overall aim is to produce high quality drawings. We present a system based on this approach and a pilot study involving human tests. Lecturer of the Inst. of Informatics, UFG-Brazil. PhD scholarship of CAPES-Brazil.

Uma introdução à visualização de informaçõesPalavras-chave: Dados abstratos, apresentação de informações, descoberta de informações Resumo Visualização de Informações é uma área emergente da Ciência que estuda formas de apresentar dados abstratos visualmente de tal modo que relações entre os mesmos são melhor compreendidas ou novas informações possam ser descobertas. O presente artigo discute vários aspectos relacionados à apresentação visual de dados e introduz técnicas efetivas e bem conhecidas para visualização de informações. As técnicas estudadas aqui têm aplicações práticas nos diversos campos da Ciência. O trabalho também aborda alguns dos desafios atuais da área de Visualização de Informações.
