Dygraphs Dynamic Zooming
            Examples demonstrating how to dynamically load down-sampled data, while zooming and panning, without modifying dygraphs.
            Demos and Notes
            
                - Example 1 - Loading down-sampled data while zooming, without modifying dygraphs
 
                - Example 2 - Similar to example 1, but also has selectable range
 
                - Example 3 - Workaround for pan interaction handling
 
                - Example 4 - Same as example 3, but verifies with multiple graphs
 
                - Example 5 - More complex example showing multiple independent series & 2nd y-axis
 
                - Example 6 - Shows  the technique is compatible with live continuous data
 
                - Example 7 - Same as example 3, but shows with annotations
