Seasonal Chart for Alabama Moths

I've been experimenting with different ways to illustrate seasonal presence of moths uploaded to iNaturalist, loosely basing it on the eBird Bar Chart which shows weekly bird data throughout the year. Each month is divided into the following day lengths: 7 | 7 | 7 | 7-10, with the last week being longer to account for varying month lengths. So after downloading the data from the Moths of Alabama project and configuring observation dates to match the weekly periods, the following result provides a concise summary through October 18, 2019:

Moths of Alabama Seasonal Chart

Version 2 with numbers

Drawbacks:
-Current chart shows both adult and larval life stages. As far as I know there is no way to download annotation fields with the data exports.
-Updating is a bit of a hassle as it has to be recreated from a new download; perhaps there are ways via API tools to create something that auto-updates, but I know nothing about that type of programming.
-Sort is currently alphabetic on scientific name; Hodges number/taxonomic would probably be better so may try that in the future.

Overall I've enjoyed looking through it to compare seasonal patterns as well as look for errors in the data. Feel free to comment with suggestions.
