Dashboard Auto-Generation (Client Edition)

Core Principle

Show first, refine later. Never ask "what do you want to see?" - analyze the data, detect patterns, and build a professional dashboard immediately.

Client-Ready Design: Clean, professional styling with neutral colors and universal branding. No CURV-specific elements. Ready to share directly with clients.

When to Activate

Activate this skill when user:

• Uploads a data file (CSV, Excel, JSON, TSV)
• Says "analyze this data"
• Asks for a "dashboard" or "report"
• Wants to "visualize" or "understand" data
• Mentions PPC, sales, analytics, or business metrics
• Requests "client-friendly" or "professional" dashboard
• Wants to share analysis with external stakeholders

Do NOT ask questions - just build the best dashboard you can from the data.

Modern Design System (Actual n8n Tokens)

CRITICAL: Complete CSS Variables (Copy Exactly)

Every dashboard MUST start with these exact n8n design tokens in the <style> tag:

:root {
  /* n8n colors - extracted from n8n.io */
  --color-crow: rgba(25, 9, 24, 0.94);

Auto-Detection Patterns

1. PPC / Advertising Data

Detect columns like:

• Placement, Campaign, Ad Group, Keyword, Search Term
• Impressions, Clicks, Spend, Cost Per Click (CPC)
• Sales, Revenue, ROAS, ACOS, CTR, Conversion Rate
• Orders, Units, Add-to-Cart, Cart Adds

Auto-generate tabs:

1. OVERVIEW - 6 key metrics + top performers table
2. EXPLORER - Searchable/filterable table with all campaigns/keywords
3. FUNNEL - Impressions → Clicks → Cart Adds → Purchases (with CVR)
4. INSIGHTS - Key findings, opportunities, recommendations

2. Sales / E-commerce Data

Detect columns like:

• Date, Product, SKU, Category, ASIN
• Units, Revenue, Profit, Price
• Orders, Customers, Sessions
• Returns, Refunds

Auto-generate tabs:

1. OVERVIEW - Revenue, units, AOV, profit metrics
2. EXPLORER - Product performance table with filters
3. FUNNEL - Sessions → Views → Cart → Purchase (if session data)
4. INSIGHTS - Low stock, high return rate, underperformers

3. Analytics / Traffic Data

Detect columns like:

• Date, Source, Medium, Campaign, Keyword
• Sessions, Users, Pageviews, Bounce Rate
• Conversion Rate, Goal Completions, Events
• Avg Session Duration, Pages per Session

Auto-generate tabs:

1. OVERVIEW - Sessions, users, CVR, bounce rate
2. EXPLORER - Source/medium breakdown with filters
3. FUNNEL - Landing → Engagement → Conversion
4. INSIGHTS - High bounce sources, conversion opportunities

4. Financial / Business Data

Detect columns like:

• Date, Account, Category, Transaction Type
• Amount, Debit, Credit, Balance
• Vendor, Customer, Invoice

Auto-generate tabs:

1. OVERVIEW - Total income, expenses, profit, cash flow
2. EXPLORER - Transaction table with filters
3. NO FUNNEL - Not applicable
4. INSIGHTS - Top expenses, late invoices, cash flow issues

Tab System (When to Use)

Use Tabs When:

• Dataset has >100 rows (need explorer for search/filter)
• Data supports funnel visualization (impressions→clicks→conversions)
• Multiple insight types exist (opportunities, trends, recommendations)

Single Page When:

• Dataset <50 rows (all fits on overview)
• Simple report with few metrics
• No funnel or exploration needed

Overview Tab (Always Required)

Structure:

1. Performance Summary Section (4-6 large metric cards)
2. Top Performers Table (top 10 by primary metric)
3. Key Insights Section (3-5 bullet points)

Metric Cards (Modern n8n Style - 3 Columns):

<div class="metrics-grid">
    <div class="metric-card">
        <div class="metric-content">
            <p class="metric-label">IMPRESSIONS</p>
            <p class="metric-value">50.9K</p>
            <p class="metric-detail">Brand share: 1.8%</p>
        </div>
        <div class="metric-footer">
            <span class="percentage positive">+12.5%</span>
            <span class="period">vs last period</span>
        </div>
    </div>
    <!-- Repeat for other metrics -->
</div>

Metric Card Styling (3 Equal Columns - Using n8n Tokens):

.metrics-grid {
    display: grid;
    grid-template-columns: repeat(3, 1fr);  /* EXACTLY 3 columns, equal width */
    gap: var(--hspace-lg);
    margin-bottom: var(--vspace-xxl);
}

@media (max-width: 1024px) {
    .metrics-grid {
        grid-template-columns: repeat(2, 1fr);  /* 2 columns on tablets */
    }
}

@media (max-width: 640px) {
    .metrics-grid {
        grid-template-columns: 1fr;  /* 1 column on mobile */
    }
}

.metric-card {
    background: var(--color-ink-black);
    backdrop-filter: blur(20px);
    border: 1px solid var(--color-ink-black-3);
    border-radius: var(--border-radius-lg);
    padding: var(--hspace-xl);
    box-shadow: var(--shadow-card);
    transition: box-shadow 0.5s ease, border-color 0.5s ease, transform 0.3s ease;
    position: relative;
    overflow: hidden;
}

.metric-card::before {
    content: '';
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    height: 2px;
    background: linear-gradient(90deg, transparent, var(--color-new-love), transparent);
    opacity: 0.4;
}

.metric-card:hover {
    transform: translateY(-8px);
    box-shadow: var(--shadow-card-hover);
    border-color: var(--color-new-love);
}

.metric-content {
    margin-bottom: var(--vspace-lg);

    font-weight: 500;
    color: var(--color-new-love);
    margin: var(--vspace-sm) 0;
    line-height: 48px;

    justify-content: space-between;
    align-items: center;
    padding-top: var(--vspace-lg);
    border-top: 1px solid var(--color-ink-black-3);
}

    font-size: 14px;
    font-weight: 400;
    padding: var(--vspace-1) var(--hspace-sm);
    border-radius: var(--border-radius-sm);
    line-height: 21px;
}

.percentage.positive {
    background: rgba(16, 185, 129, 0.2);
    color: #10b981;
}

.percentage.negative {
    background: rgba(239, 68, 68, 0.2);
    color: #ef4444;
}

.period {
    font-size: 14px;
    color: var(--color-white-3);
    font-weight: 400;
    line-height: 21px;
}

Explorer Tab (When >100 Rows)

Structure:

1. Search Bar (filter across all text columns)
2. Performance Legend (color-coded badges)
3. Sortable Table (click headers to sort)
4. Pagination (10/20/50 per page)

Search Implementation:

<div class="explorer-controls">
    <input type="text" id="search-input" placeholder="Search..." class="search-input">
    <select id="per-page" class="per-page-select">
        <option value="10">10 per page</option>
        <option value="20">20 per page</option>
        <option value="50">50 per page</option>
    </select>
    <span class="results-count">Showing <strong id="count">0</strong> results</span>
</div>

Search & Filter Implementation

const searchInput = document.getElementById('search-input');
const tableBody = document.getElementById('table-body');
const resultsCount = document.getElementById('count');

searchInput.addEventListener('input', (e) => {
    const searchTerm = e.target.value.toLowerCase();
    const rows = tableBody.querySelectorAll('tr');

    let visibleCount = 0;
    rows.forEach(row => {
        const text = row.textContent.toLowerCase();
        if (text.includes(searchTerm)) {
            row.style.display = '';
            visibleCount++;
        } else {
            row.style.display = 'none';
        }
    });

    resultsCount.textContent = visibleCount;
});

Sortable Table Implementation

document.querySelectorAll('.sortable').forEach(header => {
    header.addEventListener('click', () => {
        const column = header.getAttribute('data-column');
        const rows = Array.from(tableBody.querySelectorAll('tr'));
        const isAscending = header.classList.contains('asc');

        rows.sort((a, b) => {
            const aVal = a.querySelector(`[data-column="${column}"]`).textContent;
            const bVal = b.querySelector(`[data-column="${column}"]`).textContent;

            // Numeric sorting
            if (!isNaN(aVal) && !isNaN(bVal)) {
                return isAscending ? aVal - bVal : bVal - aVal;
            }
            // Text sorting
            return isAscending ? aVal.localeCompare(bVal) : bVal.localeCompare(aVal);
        });

        tableBody.innerHTML = '';
        rows.forEach(row => tableBody.appendChild(row));

        document.querySelectorAll('.sortable').forEach(h => h.classList.remove('asc', 'desc'));
        header.classList.add(isAscending ? 'desc' : 'asc');
    });
});

File Naming Convention

[dashboard-name]-[client-name]-[date].html

Examples:
- performance-analysis-acme-corp-2025-10-19.html
- sales-dashboard-client-a-2025-10-19.html
- ppc-report-q4-2025-10-19.html

• All tabs functional (if multi-tab)
• Search and sort working in Explorer
• Color-coded performance indicators
• Modern n8n-inspired design (dark gradient background, purple/blue accents)
• 3 equal-width metric cards per row (grid-template-columns: repeat(3, 1fr))
• NO emoticons anywhere in the dashboard
• Glassmorphic cards with backdrop-filter blur

⚠️ OUTPUT FORMAT:

• Must be standalone HTML file
