NYC Street Trees
The NYC Streets Trees is an interactive visualization created using jcanvas and jquery.
The visualization shows the numbers of different trees present in the five boroughs of NYC. The reason I wanted to talk about this visualization is because its creativity and use of customized idioms which i believe is mainly possible due to the usage of jquery and jcanvas.
The visualization shows the different variety of trees present in NYC streets segregated by boroughs. Each borough is represented by a bar, the length of which represents the number of trees and each bar is in turn is divided by the volume of different trees. The visualization is also interactive, if we select one tree then that tree is highlighted across the visualization.
Each tree is represented by a picture of the tree which would help the audience in identifying the tree when they walk the streets of NYC. We can clearly see that Queens has the most number of street trees and Manhattan the least which can be expected. Most street trees are Maples.
I believe that the visualization is unique in its usage of idioms which are customised by using jquery and jcanvas. I believe a similar visualization in Tableau would have restricted the author.
To Summarize even though the visualization is missing some key elements of claim, action, audience the author has done an excellent work in visualization using jquery and jcanvas and I could relate this with the discussion in class about using programming languages and separation of tool and task.
