USDA Nutrients in Parallel Coordinates

Getting the Data

The USDA National Nutrient Database is the standard reference for nutritional contents of food in the United States.

The data is structured as a fact table of nutrient quantities and lookup tables for food/nutrient descriptions. The data comes in a CSV format with the following variations:

  • Tildes ~ are used instead of quotes "
  • Carets ^ are used instead of commas ,

To get started quickly, export from the Nutrient Explorer. This CSV will contain the food names and nutrient headers in a standard CSV format suitable to loading into a visualization with d3.csv
