Hi,
logstalgia is pretty complex application. It will take a lot of time and money to do something close to that with all fuctions.
If you need just a connection to D3.js graph which will do the same animation, it is much more easier. But also depends of what is on the start: the data source and format, number of options to implement (for example, overall speed, form, colors, traces shape and etc. - all of this can be adjustible and each parameter requires a time to implement and test).
So, please, describe more detailed what you want to see finally.
BR,
Andrew
