Result CSV-data from HP 3458A


* RPI accesses DMMs via GPIB and reads data.
* Data is formatted by python script into DSV string and written/append to file on FTP
* DSV-file is visible publicly on
* Page runs D3.js javascript library to read DSV file test.log to input data
* D3.js plots SVG graph online :)
