Mike Bostock has written upwards a swell introduction into the unlike methods that you lot tin purpose to compare the deviation betwixt 2 unlike values inward a mapped information visualization. To illustrate the methods of comparing he has used Deaths from Alcohol Use Disorders inward 1980 together with 2014. To illustrate the deviation inward the issue of deaths from alcohol betwixt these 2 dates he has created a serial of interactive maps, each of which uses a unlike method to visualize the same data.
Methods of Comparison, Compared is published on Observable, Mike's platform for exploratory information analysis. Observable is non alone a platform for information analysis, visualization, together with exploration. It is likewise a platform for instruction together with sharing techniques inward coding together with creating meliorate information visualization. 'Methods of Comparison, Compared' is a swell event of this, every bit it non alone includes a issue of interactive choropleth maps simply likewise explores together with explains the methodology used inward their creation.
In comparing the alter inward the issue alcohol related deaths inward each U.S. of America county betwixt 1980 together with 2014 it is possible to purpose a issue of unlike methods. 'Methods of Comparison, Compared' shows 3 unlike choropleth maps, each of which uses a unlike method. These are a map showing the unproblematic deviation inward the issue of deaths betwixt the 2 dates, a moment map which shows the relative alter together with a 3rd map which shows the ratio.
Each method results inward a unlike mapped visualization of the same data. Each method has its ain advantages together with disadvantages.
