Connected Scatterplot (Lines with Custom Paths)
|
|
-----------------------------------------------
|
|
|
|
This example show how the order encoding can be used to draw a custom path. The dataset tracks miles driven per capita along with gas prices annually from 1956 to 2010.
|
|
It is based on Hannah Fairfield's article 'Driving Shifts Into Reverse'. See https://archive.nytimes.com/www.nytimes.com/imagepages/2010/05/02/business/02metrics.html for the original.
