Interactive Guide: Arrival at Lien Khuong (DLI) Airport https://cdn.tailwindcss.com https://cdn.jsdelivr.net/npm/chart.js Goal: Inform, Compare -> Viz: HTML/CSS flowcharts -> Interaction: Toggled visibility based on user’s visa type selection. Justification: Visually separates and clarifies the two distinct processes, making them easier to digest than paragraphs of text. – Report Info: Long queues at immigration -> Goal: Persuade -> Viz: Chart.js Bar Chart -> Interaction: Visual comparison of ‘Standard Wait Time’ vs. ‘Expedited Service’. Justification: A simple bar chart provides a high-impact, immediate understanding of the time-saving benefit, which is more powerful than just stating it. – Report Info: Pre-arrival checklist, airport info -> Goal: Organize secondary info -> Viz: HTML/CSS Accordion -> Interaction: Click to expand/collapse. Justification: Keeps the primary focus on the arrival process and service benefits, while making detailed information accessible without cluttering the initial view. – Report Info: Trust elements (experience, guarantees) -> Goal: Build credibility -> Viz: Styled HTML cards with Unicode icons. Justification: Breaks up text and makes trust points scannable and visually appealing. –> body { font-family: ‘Inter’, sans-serif; } .flowchart-step { position: relative; padding: 1rem; border-radius: 0.5rem; text-align: center; transition: all 0.3s ease; } .flowchart-step:not(:last-child)::after { content: ‘→’; position: absolute; top: 50%; right: -1.75rem; transform: translateY(-50%); font-size: 2rem; color: #9ca3af; } @media (max-width: 768px) { .flowchart-step { margin-bottom: 2rem; } .flowchart-step:not(:last-child)::after { content: ‘↓’; top: 100%; left: 50%; right: auto; transform: translateX(-50%); font-size: 2rem; } .flowchart-step:last-child { margin-bottom: 0; } } .tab-button.active { background-color: #0d9488; color: white; border-color: #0d9488; } .hidden-section { display: none; } .accordion-content { max-height: 0; overflow: hidden; transition: max-height 0.5s ease-in-out; } document.addEventListener(‘DOMContentLoaded’, function() { const btnEvisa = document.getElementById(‘btn-evisa’); const btnVoa = document.getElementById(‘btn-voa’); const pathEvisa = document.getElementById(‘path-evisa’); const pathVoa = document.getElementById(‘path-voa’); const tabs = [btnEvisa, btnVoa]; const paths = [pathEvisa, pathVoa]; function selectTab(selectedBtn, selectedPath) { tabs.forEach(btn => btn.classList.remove(‘active’)); paths.forEach(path => path.classList.add(‘hidden-section’)); selectedBtn.classList.add(‘active’); selectedPath.classList.remove(‘hidden-section’); } btnEvisa.addEventListener(‘click’, () => selectTab(btnEvisa, pathEvisa)); btnVoa.addEventListener(‘click’, () => selectTab(btnVoa, pathVoa)); // Auto-select the first tab on load selectTab(btnEvisa, pathEvisa); // Accordion Logic const accordionItems = document.querySelectorAll(‘.accordion-item’); accordionItems.forEach(item => { const header = item.querySelector(‘.accordion-header’); const content = item.querySelector(‘.accordion-content’); const icon = item.querySelector(‘.accordion-icon’); header.addEventListener(‘click’, () => { const isExpanded = content.style.maxHeight && content.style.maxHeight !== ‘0px’; if (isExpanded) { content.style.maxHeight = ‘0px’; icon.classList.remove(‘rotate-180’); } else { content.style.maxHeight = content.scrollHeight + ‘px’; icon.classList.add(‘rotate-180’); } }); }); // Chart.js – Wait Time Comparison const ctx = document.getElementById(‘waitTimeChart’).getContext(‘2d’); new Chart(ctx, { type: ‘bar’, data: { labels: [‘Standard Arrival’, ‘With Expedited Service’], datasets: [{ label: ‘Estimated Time in Minutes’, data: [60, 10], backgroundColor: [ ‘rgba(239, 68, 68, 0.6)’, ‘rgba(13, 148, 136, 0.6)’ ], borderColor: [ ‘rgba(239, 68, 68, 1)’, ‘rgba(13, 148, 136, 1)’ ], borderWidth: 1 }] }, options: { responsive: true, maintainAspectRatio: false, plugins: { legend: { display: false }, title: { display: true, text: ‘Estimated Time from Disembark to Baggage Claim’, font: { size: 16 } }, tooltip: { callbacks: { label: function(context) { return context.dataset.label + ‘: ‘ + context.parsed.y + ‘ min’; } } } }, scales: { y: { beginAtZero: true, title: { display: true, text: ‘Minutes’ } } } } }); });
