This free innovation.world choropleth world map tool permits to visualize and compare any country-by-country data directly in your browser. With no technical background required, paste raw lists, or type or import tabular data into an editable spreadsheet, instantly seeing those numbers come alive as a color-coded world map. The flexible controls support customized color scales, map projection, thresholds, and units, making it effortless to highlight trends across borders in a form that’s both rigorous and easy to read.
Engineers can use the map to compare variables such as national power grid capacities, average broadband speeds, or renewable energy production. Marketers can visualize distribution reach, consumer adoption, ad impressions, or sales by territory at a glance, identifying new opportunities or gaps. Economists deploy the tool to present trade volumes, inflation rates, food imports, R&D spending, or tech workforce by country—in short, any dataset where seeing the spread and contrast among nations aids understanding and communication. All it takes is a copy-paste or spreadsheet edit, and the map translates any column of numbers into geographic insight.
A choropleth map is a type of map that uses differences in color shading, patterns, or symbols within geographic areas (such as countries, regions, or states) to represent the value of a particular variable or statistic. Examples: each country might be shaded darker or lighter depending on its exports, internet penetration, CO₂ emissions, energy use, or any numeric value you want to display.
It shall be used as an interactive global choropleth map maker, a country data heatmap generator, an international statistics mapping tool, a country comparison map creator, a global data spreadsheet to map, a universal country value map, a world ranking color map tool, a visual country analysis dashboard or as an international indicators map builder.
Population by Country
This original innovation.world tool is made possible thanks to the D3, the TopoJSON (and its World Atlas), and the Jspreadsheet CE libraries.
Note: the country population map is an example to provide a template for the country list. The population values are old estimations and should not be used as if accurate, and are intended to be replaced by your own values and analyses.
Tips for Best Usage
- Move the map to center around the region of interest. Pinch in or out or mouse-scroll to zoom in or out.
- Do not modify the ISO 3166-1 numeric codes for countries. These three-digit codes (e.g., ‘840’ for USA) ensure every line, spreadsheet row, and column is mapped to the correct geography, avoiding errors caused by ambiguous or unusual country names.
- If using the text version, your data must follow the given format. If using the spreadsheet versions, your data must start in cell A1, with no heading.
- For countries to be ignored (grayed out) in the map, you can either:
- Remove their line in the textarea, column/row in the spreadsheet, or
- Leave their value cell blank (not 0, which is interpreted as a true zero value), or equal to ”.
- Choose the most convenient input method for your data source:
- Textarea: fast for pasting or editing a classic country list, ideal for quick changes or data from a text/CSV source.
- Horizontal spreadsheet: easy to paste transposed data (values as a row), good for wide tabular datasets.
- Vertical spreadsheet: the easier for working with long country lists as rows (as in Excel), especially when copying blocks from your existing reports or tables.
- Switch input modes at start, as editing one mode does not affect others.
- Customize map projection to suit your application:
- Mercator projection: preserves straight longitude/latitude, helpful for navigation, but distorts and increases a lot the polar areas. Widely used in business or school maps.
- Natural earth projection: reduces area distortion. Preferred for presentations, demographics, and economic data by territory size.
- Adjust the color gradient and value thresholds.
- Set the best color ramp curve for best differentiation:
- Linear: changes color evenly with value.
- Exponential: makes high values stand out even more.
- Logarithmic: makes low and midrange values more distinct (in the provided population example, this is likely what should be used to highlight differences appart from China and India).
- Use spreadsheets for complex edits or paste operations. Copy a Excel/Google Sheets column or block of country data directly into the vertical/horizontal spreadsheet.
- After switching data source or edits, always hit “Update Map”. The map only reflects changes after you press the button.
