Those are great examples of a classic Sankey chart. The problem is that I want something that takes the classification of the first bar and goes to several continuous features, instead of categorical features.
In this classic case, the first bar (shipping port) goes into a second bar with a different classification (survival), and then from that second bar it goes to a third bar with a different category (class).
With that same data, I would like something like a first bar (shipping port) that goes to average age and then average income of the passenger, where there is only one line per port that moves through the features with no category change.
The chart is actually a Parallel Coordinates Graph. Searching for it I was able to find the mothod to created it.
