Supporting large-scale geographical visualization in a multi-granularity way

Abstract

© 2018 Association for Computing Machinery. Urban data (e.g., real estate data, crime data) often have multiple attributes which are highly geography-related. With the scale of data increases, directly visualizing millions of individual data points on top of a map would overwhelm users' perceptual and cognitive capacity and lead to high latency when users interact with the data. In this demo, we present ConvexCubes, a system that supports interactive visualization of large-scale multidimensional urban data in a multi-granularity way. Comparing to state-of-theart visualization-driven data structures, it exploits real-world geographic semantics (e.g., country, state, city) rather than using gr..
