HousePrices Visualization This demo uses treemaps to explore spatial and temporal variation in house prices in London.
It formed a part of our contribution to the GeoViz Digital City Workshop in Hamburg, 3-5 March 2009 (
abstract).
The application demonstrates how 2D ordering and layout in treemaps can be exploited to explore spatial and temporal patterns in data. London property sales over the past eight years are used as a case study.
bookScraper: Vocabulary Cluster Graph Our interactive 'clustering' graph has been designed to help compare documents in the bookScraper collection based on the similarity of their vocabularies.
The more similar two publications are, the closer they appear to one another in the graph.
Groups of books with similar vocabularies cluster.
bookScraper: Vocabulary TreeMap Our interactive treemap allows us to explore the 100 most important words in each of the bookScraper publications.
Treemaps are used to show hierarchical information through nested rectangles. The size of each rectangle represents some quantity - numbers of times that words occur in the collection here.
Rectangle positions show the relationships between different levels of the hierarchy and their colours relates to numeric values.
In this interactive application the hierarchy shows words, within (occurring in) books, within (written by) authors.
LandSerf 2.2 released LandSerf is a freely available Geographic Information System (GIS) for the visualisation and analysis of surfaces.
Applications include visualisation of landscapes; geomorphological analysis; gaming; GIS file conversion; map output; archaeological mapping and analysis; surface modelling and many others.
LandSerf runs on any platform that supports Java (Windows, MacOSX, Unix, Linux etc.)
