What does this tool do?

It computes natal positions and house cusps with computeNatalChart and draws an SVG zodiac wheel.

Which house systems are supported?

Placidus, Whole Sign and Equal. Placidus falls back to Equal above ±66° latitude.

Is birth data sent anywhere?

No. Time, timezone and coordinates never leave the browser.

Why do Placidus houses look uneven?

Placidus uses time-based semi-arcs, so cusp spacing varies with latitude and season.

About this tool

Compute planet positions and house cusps from a birth time and place, then draw an SVG zodiac wheel. Runs locally, no account. Natal Chart runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.

What this tool does not do

Natal Chart is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
