Q&A
Question by group 1
Is the measure of y axis of the graph the count of crashes? Did you consider to
use something else (for instance the number of fatalities)?
A: Yes it is. We thought about it, but that the most significant type of
data would have been the number of crash accidents.
Question by group 3
What would your data look like if zoomed in? Can you access information for a
certain accident?
A: If you zoom in you'll see the single markers displayed. There is a tooltip
explaining the accident appearing when you tap a crash marker.
Question by group 4
How does multiple states reflect on the map as compared
to graph and scatter plot?
A: The map is updated with the last state picked
Question by group 5
How much granularity did you put in for age? How was the y-axis
of age mapped?
A: 10 years. Dynamically, considering the maximum age for that
set of samples.
Question by group 6
How is the clustering done on map and what amount does the
different shade represent?
A: It's a k neighbor like clusterization. Gradient is cluster density.
Question by group 7
Why does the map display aggregate and individual data when map
mode changes? Was it a bug or intentional?
A: Single data are displayed if there is no reason to cluster them. K-neighbors is
used for clusters. They are dynamically computed when position changes.
Question by group 8
Is there another way to select a state, as it seemed difficult to select a state with less values?
Also I will have to spend a couple of seconds to look around for the state. Can the state
be selected from the map?
A:
Question by group 9
How is the color of the clusters determined?
A: It is determined by the number of crashes that belong to that cluster
Question by group 10
Why didn't you choose something other than a slider for the to/from year ranges?
(Sliders are bad on the wall)
A: We implemented a custom working slider.
