This is a Binned Line Chart version of Mike Bostock's zoomable area chart. You can find his source here. The graph shows number of flights per day in the United States.
- Use the mouse-wheel to zoom in and out, and drag the slider to adjust the size of the bins.
- View with the step-after interpolation method to see the discrete bins.
This is a small demo made part-way through Matt Woelk's Masters Thesis. A video demonstration of the full version is available.
