Data Preparation
1. Grouping Measures
There are a total of 106 measures given in the data file, and it is difficult to view all the measures at a glance. In order to make the visualization simple I have grouped the measure based on their Chemical Composition and Behavior.
- A new column was added in the file chemical units of measure.csv
- Name the column as groups
- Chemical properties of each measure was studied and they were divided in 12 groups.
- Manually assigned the relevant group to each measure.
The 12 groups formed are:
