This visualization applies data-driven styling techniques from Mapbox documentation.

+
+ Technique Applied: Interpolate expressions for continuous data (quality, enrollment, literacy) and match expressions for categorical data (institution type). +
+

+ Data includes 180 educational institutions with metrics: quality scores, enrollment, literacy rates, and funding levels. +

'visible' : 'none'); + +// Enhanced approach learned +map.setFilter('layer-id', filterExpression); +``` + +The web source demonstrated layer visibility toggling.

'visible' : 'none' + ); +}); + +// My adaptation +checkbox.addEventListener('change', () => { + updateFilterState(); + applyFilters(); +}); +``` + +#### 4. Feature Property Access +```javascript +// Learned pattern for accessing feature properties in expressions +['get', 'propertyName'] // Retrieves property value from feature +``` + +### My Enhancements Beyond Web Source: + +1. **Compound Filter Expressions**: + - Used `all` operator to combine multiple filter conditions + - Implemented range filtering with `>=` and `<=` + - Multi-value filtering with `in` and `literal` + +2. **Range Sliders**: + - Extended beyond checkboxes to continuous controls + - Real-time value display and updates + - Multiple independent metric thresholds + +3. **Filter Coordination**: + - Mutual exclusivity for "All" vs specific regions + - State management across 6 filter dimensions + - Reset functionality restoring all defaults + +4. **Statistics Calculation**: + - Query rendered features after filtering + - Aggregate calculations (sum, average) + - Live dashboard updates + +5. **Multi-Layer Filtering**: + - Coordinated filters across universities and labels layers + - Maintained label visibility rules while respecting filters + +## Technical Implementation Details + +### Filter Architecture + +**Filter State Object**: +```javascript +let currentFilters = { + regions: ['all'], // Selected regions + rankingRange: [1, 120], // Min/max ranking + minPublications: 0, // Publication threshold + minCitations: 0, // Citation threshold + minFunding: 0, // Funding threshold + minNobelPrizes: 0 // Nobel prize threshold +}; +``` + +**Filter Expression Builder**: +```javascript +function applyFilters() { + let filterExpression = ['all']; // AND combiner + + // Region filter (OR within selected) + if (!selectedRegions.includes('all')) { + filterExpression.push([ + 'in', + ['get', 'region'], + ['literal', selectedRegions] + ]); + } + + // Ranking filter + filterExpression.push(['<=', ['get', 'ranking'], maxRank]); + + // Metric thresholds + if (minPubs > 0) { + filterExpression.push(['>=', ['get', 'publications'], minPubs]); + } + + // Apply to layer + map.setFilter('universities-layer', filterExpression); + + // Update statistics + updateStatistics(); +} +``` + +### UI Control Implementation + +**Checkbox Filters** (7 regions): +```javascript +regions.forEach((region, index) => { + const checkbox = createElement('input', { + type: 'checkbox', + id: `region-${index}`, + value: region, + checked: region === 'All' + }); + + checkbox.addEventListener('change', () => { + // Handle "All" mutual exclusivity + if (region === 'All' && checkbox.checked) { + uncheckOtherRegions(); + } else if (checkbox.checked) { + uncheckAll(); + } + applyFilters(); + }); +}); +``` + +**Range Sliders** (5 metrics): +```javascript +slider.addEventListener('input', (e) => { + const value = parseInt(e.target.value); + currentFilters.metric = value; + displayElement.textContent = formatValue(value); + applyFilters(); // Immediate update +}); +``` + +### Statistics Dashboard + +**Query Filtered Features**: +```javascript +function updateStatistics() { + const features = map.queryRenderedFeatures({ + layers: ['universities-layer'] + }); + + const stats = { + count: features.length, + avgResearch: average(features, 'researchScore'), + totalPubs: sum(features, 'publications'), + totalCitations: sum(features, 'citations'), + totalNobel: sum(features, 'nobelPrizes') + }; + + updateDashboard(stats); +} +``` + +This queries only the currently visible (filtered) features, enabling real-time statistics that update with every filter change. + +## Data Structure + +### University Data Model + +```javascript +{ +
