Data Intelligence Engine

Any data format. Instantly understood.

Paste messy CSV, plain English, raw JSON, a spreadsheet dump, or outright garbage. CloviAI reads your intent, cleans the data, infers the best chart type, and renders it — automatically.

Pattern Detection

CloviAI applies regex + token classifiers to detect dates, currencies, percentages, and categorical labels — even in mixed-format inputs.

Schema Inference

After cleaning, LLM-assisted schema inference maps columns to axes, detects series dimensions, and selects the optimal chart geometry — bar, line, scatter, or heatmap.

FAQ

Questions, answered

Everything you need to know before your first API call.

Over 25 types — the Chart.js core set (bar, line, area, pie, donut, scatter, radar, polar, bubble, stacked, horizontal bar) plus Apache ECharts specialty types like heatmaps, gauges, funnels, waterfalls, and OHLC candlesticks. Every type renders server-side from the same single POST request.
All of them. Post clean JSON for full control, or hand CloviAI a messy CSV paste, a spreadsheet dump, plain-English prose, or a raw SQL result — the Data Intelligence engine cleans it, infers the schema, and picks the best chart type automatically. The no-code builder also accepts drag-and-drop CSV and Excel files.
PNG, SVG, and WebP image output, plus Base64 inline and CDN-hosted URLs on paid tiers. Charts are returned as an image URL in under a second, with no watermarks on any tier — including Free.
Yes. Drop in an image URL anywhere, or use interactive iframe embeds on Pro and above. For multi-tenant dashboards, server-issued signed JWT tokens let you distribute tenant-specific charts without ever exposing your API key.
On Pro and Enterprise, charts can be served from your own branded CDN subdomain (e.g. charts.yourproduct.com) so the entire experience stays under your brand — no CloviCharts URLs visible to your end users.
Re-post your data and a fresh chart renders in under a second. Pair CloviCharts with CloviFlow to schedule automatic regeneration from any data source, or use the batch API to refresh up to 10 charts in a single call.
