Develop a chart that provides a detailed breakdown of the vocabulary a user has mastered. This chart should categorize vocabulary based on several key criteria, including language level (e.g., beginner, intermediate, advanced), frequency of appearance (e.g., common, rare), and lexical type (e.g., words, phrases, idioms). The chart should differentiate between vocabulary learned through the app and those marked as known by the user. This visualization will help users better understand the diversity and depth of their vocabulary knowledge, offering insights into areas of strength and potential gaps.
