The html needs d3.min.js #2
Description
There is a line in the index.html file: <script src="d3.v3.min.js"></script> In order to make the web page appear, that JavaScript file or an equivalent needs to be in the html directory. I used d3.min.js from https://gist.github.com/ndarville/7075823 and changed index.html accordingly.
Another minor problem is that csv_clear.py has the columns mixed up. It should be:
file.write("index,date_time,date,time,hex,flight,alt_baro,alt_geom,gs,track,geom_rate,squawk,emergency,category,nav_qnh,nav_altitude_mcp,lat,lon\n")
