Data visualization of Aberystwyth Shipping Records

In a previous post, I described the shipping records for vessels registered at the port of Aberystwyth, transcribed by volunteers and released in digital form by the National Library of Wales.

I have used openpyxl to read the files (released as Excel spreadsheets) in Python. I have uploaded the code at (the data itself should be downloaded from the National Library of Wales site).

I have uploaded results at and have recently extended this to include plots made using matplotlib, which are presented below (and will be put up in some form at the neocities page soon).

The earliest and latest dates recorded for each vessel.

The joining and leaving dates for every mariner recorded (who has parsable dates)
