Coffee Roasting Profiler
Shiny
Data Viz
An ameateur coffee roaster, I made this dashboard to visualize my coffee roasts.
What I learned
While I use Artisan, an open-source software used to record coffee roasts, I wanted an interactive chart to explore my roasts.
The tricky part was adding the RoR (rate of return) curves (the blue and purple ines) onto the graph as this is calculated via an algorithm written in Python inside Artisan. I found this piece of code and rewrote part of it so it would work for my app. I used the reticulate package so the app can read Python code.
Highlighted packages
The dashboard uses reticulate, formattable, plotly, and DT under a golem framework.
