Module# 1: First day attendence + a recent eye-catching visual analytics

Hello everyone!

You can find my other blogs here -> Mihir Patel

One of the recent visual analytics which have caught my attention is this:





It is from Northeastern University and was visually presented by Dr. Pedro Cruz, Dr. John Wihbey, Dr. Avni Ghael, and Dr. Felipe Shibuya. This graph represents U.S. Immigration from 1790 up until 2016. Each of the tiny dot in this graph corresponds to 100 immigrants.

Here is the legend consisting countries associated with color palette:




And then the cartogram below which divides U.S. immigration across 50 states, showing immigration and natural born.



The reason why this particular data visualization caught my attention is due to how unique it is. This type of graph is called Dendrochronology. Graphs such as this is generally used to calculate the age of a tree. Basically, an Ecologist looks at an aging tree, cuts its trunk and then counts the ring subsided within the trunk. But here, each ring represent the number of immigrants in U.S. in thousands. It is representing connection between human and nature, and data and numbers. Hard work and detail are clearly pop out from this graph, that's why it caught my attention. The graph actually came out in 2018. But I saw it in September 2019 while reading some data visualization articles.

You can visit here to see the simulated version of the graph above. And if you would like to more about the research itself, head over here.

Thanks and good luck to you all this semester!
