Design

Constraint: language agnostic

1. Should work with any language

2. Or no language at all: drag and drop & terminal

3. Incentive for clients in many languages

4. Avoid trapping myself into the idioms of a language -> standards

Constraint: language agnostic

Not a Single Page Application

Constraint: open source

1. Can be installed, not an app only

2. Users! How to handle authentication, security?

3. Data: local, global, replication?

System

Ugly but works for now!

yes, hard-coded for debug

plot.js:46026 Uncaught InvalidStateError: Failed to execute 'send' on 'WebSocket': Still in CONNECTING state.

Recap
