Users previously needed to manually write ChartSpec JSON or configure API keys before creating charts. The application now enables Smart Mode by default, allowing immediate natural language chart generation without setup.

Changes

State initialization (chartspec/main.js)

  • Set smartMode: true as default instead of false
  • First-time users now land in Smart Mode automatically

Settings persistence (chartspec/main.js)

  • Enhanced loadSettings() to distinguish between no preference (default to Smart Mode) and explicit user choice
  • Handles three cases: 'true' (keep enabled), 'false' (user disabled), null (use default)

Onboarding (chartspec/main.js)

  • Added showWelcomeMessage() to explain active mode on first launch
  • Message shown once via localStorage flag

Documentation (README.md)

  • Reordered modes: Smart Mode (Default) → LLM Mode → Local Mode
  • Updated Getting Started to emphasize zero-setup flow
  • Added Smart Mode command examples

User flow

// Before: Manual ChartSpec or API key required
// After:
1. Open app → Smart Mode active
2. Select dataset
3. Type: "show bar chart of Revenue by Region"
4. Chart renders instantly

Backward compatibility

Existing user preferences respected via localStorage:

  • Users who explicitly disabled Smart Mode → stays disabled
  • Users with saved API keys → can toggle back to LLM Mode
  • Local Mode → still available
Original prompt

Ok so chart works but one needs to define the chartspec objective is for the chat interface to drive the gen of chartspec.

The comment on line 846 is misleading. It states "Check if this is a first-time user (no saved chat history)" but the code actually checks localStorage.getItem('chartspec_welcome_shown'), which is a dedicated flag for the welcome message, not chat history. The comment should be updated to accurately reflect what the code does, e.g., "Check if the welcome message has been shown before".

Suggested change
// Check if this is a first-time user (no saved chat history)
// Check if the welcome message has been shown before
