What Is a Tile Map?

A tile map, also known as a tile grid map or grid cartogram, replaces the irregular geographic shapes of regions with equal-sized geometric tiles, typically squares or hexagons, arranged in positions that approximate the real-world geographic layout. Unlike choropleth maps where geographically large regions like Alaska, Russia, or Australia visually dominate the display regardless of the metric being shown, tile maps give every region exactly the same visual weight. This means that small but densely populated or economically significant regions like Rhode Island, Singapore, or Luxembourg receive the same visual prominence as their geographically larger counterparts. Each tile displays a region label and is colored according to the data value it represents. The equal-area constraint eliminates the large-area bias that makes traditional maps misleading for per-capita, per-region, or any non-area-based metric, creating a fairer and more accurate visual comparison.

What Data You Need for a Tile Map

Two columns: a US state two-letter code (CA, TX, FL, NY...) and a numeric value to encode by color. The tool places each state on a built-in 8x11 US tile grid that approximates real geography — you do NOT supply row/column coordinates. If every label is a recognized US state code, you get the true US layout; any non-US or unrecognized labels fall back to an arbitrary square grid filled in input order (no geographic meaning). Example rows: CA 6.5, TX 8.1, NY 5.2.

When to Use a Tile Map

Use tile maps whenever geographic area is not the variable you are visualizing and you want to prevent large-area bias from distorting viewer perception. They are widely used in political reporting for election results by state or constituency, where every state or district deserves equal visual weight regardless of land area. Public health organizations use them to compare vaccination rates, disease prevalence, or healthcare access metrics across countries or regions on an equal footing. Business intelligence teams use tile maps to compare sales performance, market penetration, or customer satisfaction scores across equally important territories. They are effective for any KPI comparison across geographic units of unequal size, such as GDP per capita by country, crime rates by state, or education spending by region. Tile maps are particularly popular in data journalism and editorial design because they combine geographic context with fair visual representation.

Where a Tile Map Works Best

Showing a metric across all 50 US states without Alaska, Rhode Island, or DC being visually lost due to area differences (e.g. broadband adoption rate per state).
Election or polling results by state where each state should carry equal visual weight regardless of physical size.
Per-country KPIs across Europe where small nations like Luxembourg or Malta must remain clearly clickable and comparable.
Comparing two snapshots side by side (e.g. 2024 vs 2026 unemployment by state) using two identical tile grids for fast position-based scanning.

Tile Map Example: US Broadband Gap

A telecom analyst maps the share of households with high-speed internet across US states. On a choropleth, tiny northeastern states vanish while large western states dominate; a tile map gives every state an equal square placed by its built-in grid position.

Sample data: CA 89, TX 82, NM 74, MS 71, NJ 94, MA 93.

The lowest-coverage tiles (MS 71, NM 74) sit in the South/Mountain West while the highest (NJ 94, MA 93) cluster in the Northeast — the equal-sized, geographically-arranged grid makes the regional gap obvious without large low-coverage states overpowering small high-coverage ones.

How to Create a Tile Map Online

Step 1: Open ChartLoad and select Tile Map from the chart type menu
Step 2: Choose a predefined tile layout such as US states, world countries, or European nations
Step 3: Enter the data value for each region that will determine its tile color
Step 4: Select a sequential or diverging color scale that clearly differentiates value ranges
Step 5: Add region labels and optional value annotations inside each tile for precise reading
Step 6: Export the tile map as PNG, PDF, or SVG for data journalism, reports, and dashboards

Tile Map Best Practices & Tips

Tile maps give each geographic unit equal visual weight, eliminating the area-bias problem of choropleth maps.
Use a grid layout with one square per region so Alaska does not dominate the US map visually.
Color each tile by data value using a sequential or diverging scale, just as you would in a choropleth.
Tile maps are fairer than choropleths for per-capita data because every region gets the same visual footprint.
Add hover tooltips with exact values and region names so readers can identify tiles without memorizing the grid layout.
Use consistent tile sizes and spacing so all regions receive equal visual weight regardless of geographic area.
Tile maps are increasingly popular in US election coverage where each state tile prevents California from visually dominating Alaska.

Common Tile Map Mistakes to Avoid

Placing tiles in positions that contradict mental geography (e.g. putting Florida above Georgia) so readers can't locate states at a glance — tile order should approximate real adjacency even though shapes are dropped.
Cramming too many regions into one grid: tile maps work for ~50 US states or ~30 countries, but a 200-region world grid becomes an unreadable abstract checkerboard with no recoverable geography.
Forgetting the two-letter or abbreviated label inside each tile — unlike a real choropleth, a square gives zero shape cues, so an unlabeled tile is impossible to identify.

Frequently Asked Questions

Why use tiles instead of a real map?

Traditional maps give more visual weight to geographically large regions. Tile maps equalize this, ensuring Rhode Island is as visible as Texas — fairer for per-capita or per-region data.

What layouts are available?

US states (square and hexagon), world countries, and European countries. Custom layouts can be configured.

Can I color tiles by value?

Yes — apply a sequential or diverging color scale based on your data values, just like a choropleth but with equal tile sizes.
