Visualizing Food System Concentration and Consolidation

Visualization of the changing structure of the food system has played an important role in the Missouri School of Agrifood Studies’ research and outreach. The analogies and diagrams Missouri researchers have used to describe concentration and consolidation have aided our understanding of the extent of these phenomena, as well as their social impacts. This article discusses why visualization is effective for analyzing and presenting data. Recent advances in visualizing concentration and consolidation are described—these methods include 1) treemaps, 2) cartographic maps, 3) cluster diagrams, 4) taxonomic tree/timelines, and 5) animations. Examples utilizing data from the North American organic food industry illustrate the potential of visualization to improve analysis of recent structural changes, and to increase public awareness of the unequal distribution of power in the food system

An Interactive Bio-inspired Approach to Clustering and Visualizing Datasets

In this work, we present an interactive visual clustering approach for the exploration and analysis of datasets using the computational power of Graphics Processor Units (GPUs). The visualization is based on a collective behavioral model that enables cognitive amplification of information visualization. In this way, the workload of understanding the representation of information moves from the cognitive to the perceptual system. The results enable a more intuitive, interactive approach to the discovery of knowledge. The paper illustrates this behavioral model for clustering data, and applies it to the visualization of a number of real and synthetic datasets

AN INTERACTIVE REMOTE VISUALIZATION SYSTEM FOR MOBILE APPLICATION ACCESS

This paper introduces a remote visualization approach that enables the visualization of data sets on mobile devices or in web environments. With this approach the necessary computing power can be outsourced to a server environment. The developed system allows the rendering of 2D and 3D graphics on mobile phones or web browsers with high quality independent of the size of the original data set. Compared to known terminal server or other proprietary remote systems our approach offers a very simple way to integrate with a large variety of applications which makes it useful for real-life application scenarios in business processes
