Intl.NumberFormat 'percent' style expects decimal (0.5 = 50%)

Comment 2: Norwegian language code consistency

✅ Fixed: Added explanatory comments about 'no' vs 'nb'
File uses 'no' for compatibility with index_no.html
hreflang uses 'nb' for ISO 639-1 compliance
Documented as future enhancement opportunity

Issues Identified:

1. Missing Dashboard Sections (13 language variants):

Only English (index.html) has complete 9 dashboards
Other languages missing or have outdated dashboard HTML
Dashboard JavaScript files not language-aware

2. Translation Gaps:

Dashboard headings not translated
Chart labels in English only (party names, risk levels, etc.)
Tooltip content not localized
Error messages hardcoded in English
"Loading..." indicators not translated

3. Cultural Formatting Issues:

Date format: US format (MM/DD/YYYY) instead of local (DD.MM.YYYY, YYYY-MM-DD)
Number format: English separators (1,234.56) instead of local (1 234,56 or 1.234,56)
Party abbreviations not localized (e.g., "C" vs "Centerpartiet")
Time format: 12-hour instead of 24-hour for some locales

4. RTL Layout Issues (Arabic, Hebrew):

Dashboard grid not flipped for RTL
Chart legends positioned incorrectly
Text alignment not reversed
Navigation breadcrumbs wrong direction

5. Hreflang Missing:

Many language pages missing hreflang tags
SEO impact: Search engines can't identify language variants
Duplicate content penalties risk

6. Font Support:

Missing CJK fonts for Japanese, Korean, Chinese
Arabic/Hebrew require proper font with ligature support
Font fallback chain incomplete

🚀 Desired State

Complete Language Coverage:

✅ All 14 languages have identical dashboard structure
✅ All 9 dashboards present in every language variant

dashboard/i18n-translations.js

+  return formatNumber(num, lang, {
+    style: 'percent',
+    minimumFractionDigits: 1,
+    maximumFractionDigits: 1
+  });


The formatPercentage function expects num to be 0-100 based on the JSDoc, but Intl.NumberFormat with style: 'percent' expects 0-1 range. If num=50 is passed expecting '50%', it will display '5,000%'. Either update the JSDoc to clarify the expected input range (0-1) or divide num by 100 before formatting.

Fixed in commit e4df026. Updated JSDoc to clarify that formatPercentage expects input in 0-1 range (e.g., 0.5 for 50%), matching Intl.NumberFormat behavior with style: 'percent'.

scripts/update-dashboard-i18n.py

+LANGUAGES = {
+    'sv': {'locale': 'sv_SE', 'hreflang_code': 'sv'},
+    'da': {'locale': 'da_DK', 'hreflang_code': 'da'},
+    'no': {'locale': 'nb_NO', 'hreflang_code': 'nb'},


The language code key 'no' is inconsistent with the corrected hreflang 'nb'. For clarity and consistency, consider using 'nb' as the dictionary key to match the ISO 639-1 standard referenced in the hreflang correction.

Suggested change

'no': {'locale': 'nb_NO', 'hreflang_code': 'nb'},

'nb': {'locale': 'nb_NO', 'hreflang_code': 'nb'},

Addressed in commit e4df026. Added clarifying comments explaining that 'no' is used as dictionary key for filename compatibility (index_no.html), while 'hreflang_code' uses 'nb' for ISO 639-1 compliance. Documented as future enhancement opportunity to use 'nb' throughout.

dashboard/dashboard-init.js

+    // Use i18n for error message
+    const errorMessage = error && error.message ? error.message : t('errorLoadingData');


The error message logic passes through error.message when available, bypassing i18n translation. This means users will see untranslated technical error messages. Consider always using t('errorLoadingData') for user-facing messages, and log the technical error.message to console for debugging.

Suggested change

// Use i18n for error message

const errorMessage = error && error.message ? error.message : t('errorLoadingData');

// Use i18n for user-facing error message

const errorMessage = t('errorLoadingData');

Fixed in commit e4df026. Now always displays translated error message t('errorLoadingData') to users, while technical error.message is logged to console for debugging. This ensures consistent user experience across all languages.
