Developer Notes

• Duplicates by description in Foundation, keep most recent entry by publication date
• Inconsistent naming of nutrients between Foundation and SR Legacy, leading bland spaces (removed, use Foundation nutrition names - most up to date)
• Nutrient with nutrient_id = 2066 is missing, but still present in food_nutrients (only nan values however), dropped from the dataset
• When combining Foundation and SR Legacy, there are duplicates between the two, keep the most recent entry, but impute nans with values from the records that are about to be dropped (essentially merge the two records, favour the most recent one)
• Use inkscape to divide sheet of icons into separate .svg files. Convert .png files to .svg??
• Remove background and make svgs transparen outside of the actual icon by editing the file content and removing the background path block.
• Crop in either inkscape (keep tight) or programatically in file, can be tricky if not centered however.
• Scale and adjust boarders / background color via CSS. Use svgs only.
