Plan core functionality

[chizapoth]

The motivation is to build a set of visualization tools for a typical EHR dataset that have the following features:

• time stamps
• mixture of static and repeated measurements
• considerable amount of registration error

Hence the core functionality (for personal graphs) requires

• handling of time and static (e.g. tile + gt tables)
• QA across several tables for one person's records (e.g. within LOS? drug use BEFORE prescription?)
• compare ONE patient vs the cohort, provide some summary so that we know if he's normal or outlier

Stage 1: simply visualize what has happened (temporal events)

Stage 2: combine text, use different colors to point out errors

Stage 3: at an aggregated level, process modeling
