HTML Data flow structure

Process

1. Load JSON -> Fetch('./data.json');
2. Create DOM -> Create HTML Elements from JSON
3. Connect Logic -> Call initializePaint(data)

UI Elements

1. Navigation Links

data.navLinks.forEach(link => {
  const li = document.createElement('li');
  if (link.isCurrent) li.id = 'CurrentPage';  // Current page
  const a = document.createElement('a');
  a.href = link.href;
  a.textContent = link.text;
  // Create menu
});

2. Toolbar Controls

switch (controlInfo.type) {
  case 'color-picker':    // Picker
  case 'range':           // Slide bar
  case 'select':          // Dropdown menu
}

3. Buttons

// Fetch from JSON file
toolbarData.buttons.forEach(buttonInfo => {
  const button = document.createElement('button');
  button.id = buttonInfo.id;
  button.textContent = buttonInfo.text;
});
