TheGDB Compare tool was developed to analyze the health levels andtrends in the globe. The analysis ranged from the year 1990 to late2013 when the interactive visualization tool was applied to make agood representation of data. The tool was improved to incorporate theuse of treemaps (Arthur,2014).This data visualization method gives the viewer an opportunity tounderstand the data better as it applies a space-constrainedvisualization of the various levels and structures in the nation. Thetreemaps effectively display the attributes of leaf nodes. Thismethod uses size and color-coding as a way of representing anddifferentiating various components.
TheGDB tool uses other techniques such as the arrow diagrams and severalother charts. These methods allow the tool to compare the causes ofdifferent diseases in the globe as well as the levels and types ofrisks that the countries face. Through this tool, it is possible tocompare the conditions in different countries as well as the natureof health among various regions in the globe (Arthur,2014).Through this method, one can determine the most vulnerable areas inthe world and the magnitude of the problem.
TheGDB is a tool that helps the users to understand the data further asit provides an opportunity to investigate the patterns and thetrending conditions among the countries, by age group or gender(Arthur,2014).One can trace the change in disease patterns and determine the causesof death and impairment in a hierarchical order. This method allowsthe users to transform global view or information into specificdetails. is, therefore, a useful method for datavisualization. Through this method, one gets to understand andanalyze various types of information in an efficient way.
