I have a bunch of custom log files where each line has a timestamp, and some data points. I actually began writing my own macOS program to import and visualize these logs, but the sheer number of data points makes any charting package I try basically throw up. Each log file has tens of thousands of lines/datapoints (sometimes even hundreds of thousands, actually).
So, what could anyone recommend to visualize this data? I'm looking for mostly line/scatter charts, and don't have an issue transforming the data into some other form, as I already have a parser written.
It would be a bonus if the generated charts were interactive, so I could zoom around them etc., rather than just a static image, for example.
