Common use cases
Chart API data directly
Take the JSON an endpoint returns and turn its numeric fields into a chart without writing parsing code. Useful for quick dashboards over live data you already fetch.
Visualize metrics & events
Event streams and metrics are usually JSON arrays. Plot counts, durations, or amounts over time to see patterns that are invisible in the raw payload.
Report on nested records
Pull the array that matters out of a nested response and chart it — orders, users, or line items — to summarize a JSON dataset for people who never see the API.
Tips & best practices
The generator charts best from an array of objects that share the same keys, so each object is a data point and each key a possible axis or series. If your JSON wraps that array inside an outer object, point the tool at the array itself for the cleanest result. Use one numeric field per series and a consistent label field — a date or category — for the axis. Deeply nested values may need flattening first, since the generator reads top-level keys of each object. Keep numbers as JSON numbers, not strings like "42", so they plot on a numeric scale instead of as categories. Mixed or missing keys across objects still work but can leave gaps, so uniform records give the most reliable charts.
