Need to create multiple pie charts from multiple columns that have different total values

Solution for Need to create multiple pie charts from multiple columns that have different total values
is Given Below:

I have a table that has 50 different plants and the % concentration of 10 specific compounds. I created a new column that adds the total % amount of all compounds for the 50 products but the values are not the same. I need to create multiple pie charts showing the distribution of each compound within the different products but am not sure how to do that since the denominators are not the same. I’m new to R so if anyone could help I’d really appreciate it.
