This is some examples of using Plotly/Dash and Parquet.
Demonstration so far:
-
Plot two lines on the same plot
-
Make a histogram
-
Able to deal with >32 bit numbers
-
the scatter plot itself couldn't handle >32 bit numbers AFAICT
-
Plotting log2 of the numbers was fine
-
the Parquet write/read routines handled uint64's just fine
-
-
Write/read compressed binary parquet files
