Evaluating Cartogram Effectiveness

Algorithms for Cartogram Animation

We describe several value-by-area cartogram animation algorithms that can be used to visualize geographically distributed continuous spatiotemporal data that often occur in GIS systems. We implemented the algorithms as part of the graphical user interface of the MLPQ/GIS database system.

Efficient Cartogram Generation: A Comparison

Cartograms are a well-known technique for showing geography-related statistical information, such as population demographics and epidemiological data. The basic idea is to distort a map by resizing its regions according to a statistical parameter, but in a way that keeps the map recognizable. In this paper, we deal with the problem of making continuous cartograms that strictly retain the topolo...

Evaluating Internet technologies business effectiveness

This paper focuses on analyzing the relationship between Internet technologies and firm performance. This relationship is examined not only from the simple presence of Internet technologies, but also according to different e-business orientations: e-business orientation to customers and e-business orientation to internal processes. In addition, the relationship between Internet technologies and...

Cartogram Visualization for Bivariate Geo-Statistical Data

We describe bivariate cartograms, a technique specifically designed to allow for the simultaneous comparison of two geo-statistical variables. Traditional cartograms are designed to show only a single statistical variable, but in practice, it is often useful to show two variables (e.g., the total sales for two competing companies) simultaneously. We illustrate bivariate cartograms using Dorling...
