Frequently asked questions

Everything you need to know about building interactive maps with Mapji — map types, data, publishing, and more.

Getting started

How do I make an interactive map?

Sign up for Mapji, choose one of 9 map types, add your data by importing a GeoJSON/CSV file or connecting a Google Sheet, customize the style, and publish to your own subdomain or custom domain. No coding is required.

What is the best free map maker?

Mapji is a free, no-code interactive map maker that supports 9 map types — including heatmaps, choropleth maps, store locators, and story maps — and lets you publish to your own domain. It's free to start with no credit card required.

Do I need to know how to code to use Mapji?

No. Mapji is entirely point-and-click. You build, style, and publish maps in the browser without writing any code or installing GIS software.

How do I embed a map on my website?

Every published Mapji map can be embedded on any website with a simple iframe snippet, or you can link to it directly on your own custom domain.

Map types

What is a choropleth map?

A choropleth map shades geographic regions — countries, states, counties, or NUTS regions — by a data value, making spatial patterns in demographic, economic, or election data easy to see. In Mapji you pick a geography, join your data, and choose a color scale.

How do I make a heatmap online?

Create a Heatmap in Mapji, add your point data by uploading a file or connecting a Google Sheet, tune the radius, intensity, and color gradient, and publish. You can also weight points by a value column.

How do I build a store locator for my website?

Use Mapji's Store Locator map type. Add your locations via a Google Sheet or file upload, configure search and filter categories, then embed the locator on your website or publish it to a custom domain.

What is an isochrone map?

An isochrone map shows every location reachable within a given travel time — for example a 10-minute drive — from a starting point. It's useful for site selection, accessibility, and catchment analysis.

What is a story map?

A story map is a scroll-driven presentation that moves the map and reveals text and images as the reader scrolls through a narrative, with smooth fly-to animations between locations.

Data & sync

Can I connect a Google Sheet to my map?

Yes. For Cluster, Heatmap, Store Locator, Choropleth, and Time Slider maps you can connect a Google Sheet as a read-only, live data source. Mapji re-syncs automatically, so editing the sheet updates the map.

What data formats can I import?

You can import GeoJSON files, upload spreadsheet data, or connect a Google Sheet. Mapji auto-detects latitude and longitude columns to get you mapped quickly.

How many points can a map handle?

Mapji handles thousands of features smoothly, with a limit of 10,000 features per data source.

Publishing & domains

Can I use my own custom domain?

Yes. Publish your map to a free yourmap.mapji.com subdomain or connect your own custom domain for a fully branded experience.

Can I customize how the map looks?

Yes. Choose from built-in themes or design your own with the custom theme editor — 45+ color controls, road widths, dash patterns, label styling, and tileable fill patterns.
