This is a plot of the iris dataset.
In the music,
- Each short segment of audio corresponds to one particular iris flower. Flowers are ordered in time by increasing petal width.
- The music gets faster when irises have longer sepals.
- The pickup note gets a higher pitch when the irises have wider sepals.
- The drums turn on when petals are longer than three. (I don't know what the unit is.)
- The rhythm is different for each of the three species.
The video represents the same data.
- Each iris is plotted as a patterned rectangle. Earlier irises' rectangles remain in the video after they are played in the music, so more stuff appears in the video as time passes.
- The position of the center of the rectangle corresponds to the petal size, with x-axis corresponding to length and y-axis corresponding to width.
- The shape of the rectangle corresponds to the sepal size, with x-axis corresponding to length and y-axis corresponding to width.
