Build interactive HTML dashboards from data

Build interactive HTML dashboard from data that answers key questions at a glance

Founders who have data but no visibility into it, and need a single-file dashboard they can open in a browser and immediately see the state of their business without loading Mixpanel/Tableau/BI tool.

• · Data source: file, folder, CSV, spreadsheet, or paste
• · Topic: sales, project tracking, marketing metrics, finances, etc.
• · 3-5 key questions the dashboard should answer
• · Audience: just founder, or team/client share?

• · Single-file HTML dashboard with embedded data and charts
• · Includes: headline KPI strip, time-series chart, 2-4 breakdown charts, detail table, notes
• · Filters, hover details, sortable table, responsive layout

• · Chart.js, Apache ECharts, or D3 (embedded via CDN or inline)

• · Data structured with clear schema (columns, data types, date dimension)
• · Refresh cadence known (one-time build vs data updates expected)

• · Data quality issues (missing values, duplicates, inconsistent formats) silently ignored instead of flagged
• · Too many charts (information overload) instead of ruthless focus on 3-5 questions
• · Large datasets (>1000 rows) not aggregated, making filters slow or UI unresponsive

• · Headline numbers with trend indicators (vs prior period) before breakdown charts
• · Light background, muted colors, sparse gridlines (designed for long-session readability)
• · Number formatting attention ($1.2M not 1247392.41, +12.4% not 0.124)
• · Filters update all charts simultaneously, not disconnected
• · Hover details on every chart point, sortable table for drill-in
