I am loving Squirrel, and see a really big potential in it!
I work for IFUA Horváth & Partners (management consultant company) and I have worked a lot with Xcelcius (SAP Dashboards). Aftes flash is done, I (and the company) see that squirrel is not only a substiture for Xcelcius, but a more intuitive, beautiful and smarter tool. In Hungary (where I work) we have entered the 2020 DataViz contest with squirrel and we have won with the vizualization, and simulation capabilities of Squirrel.
The screenshots about the winning dashboard (the vizualizations are Hungarian):

I really recommentd Squirrel, it's a very easy to use, no-code tool, and with the long trial, everyone can see how it can help them.
