Douwe
WorldSizer is a free, open-source interactive mapping tool that resizes countries on a world map proportionally based on selected metrics such as population, GDP, CO2 emissions, and other World Bank indicators. Users select a metric from a dropdown, and the map instantly redraws to show which countries dominate that dimension. The tool also generates ranked lists of the top 10 largest and smallest countries for each metric. It uses a Mollweide projection to preserve area accuracy and reduce geographic distortion. Agencies can access it via web browser or fork the GitHub repository to customize or embed it into client deliverables.
Douwe is a free. InnovaAI scores it 3/10 for agency adoption, best for Strategist, Content Creator, and Researcher roles handling weekly client-facing work.

The commercial case before the tooling.
Core concepts
The mental model you need to price and scope the work.
- Reconciliation Before AutomationConcept
Reconciliation Before Automation is a framework for agencies evaluating analytics and reporting platforms. It posits that the primary value of these tools is not dashboard aesthetics or automation speed, but the accuracy of the underlying data reconciliation. Agencies often adopt platforms to save time, yet if the platform's source coverage or data freshness produces numbers that don't match the client's internal records, the time saved is negated by credibility damage. For example, a client running display ads may see platform-reported ROAS that conflicts with backend order data, as noted in recent research. Agencies should benchmark their current reporting process, identify reconciliation gaps, and only then select a platform that demonstrably closes those gaps. The framework emphasizes that recovered capacity should be invested in analysis and proactive recommendations, not just faster report generation.
- Narrative Control RatioConcept
The Narrative Control Ratio measures how much of a reporting tool's output is shaped by the agency's own commentary versus raw platform data. In an era where clients increasingly question reported numbers, agencies that simply hand over dashboards lose the ability to frame performance. The ratio is the share of report content that is narrative, insight, or recommendation, divided by the share that is automated data visualization. A high ratio means the agency controls the story; a low ratio means the tool does. For example, a PPC report that shows a pipeline number finance will not accept is a liability, not a deliverable. Agencies should benchmark their current reporting process, then use recovered capacity for proactive analysis, not just dashboard access.
- Attribution Gap VisibilityConcept
Attribution Gap Visibility is a framework for assessing how accurately an agency's reporting reflects true client performance. The gap is the difference between what platforms claim (e.g., ROAS from ad networks) and what backend systems confirm (e.g., CRM revenue or order data). When this gap is hidden, agencies risk presenting misleading numbers that clients or finance teams eventually question, eroding trust and threatening retainers. The framework urges agencies to quantify this gap before adopting new reporting tools, because dashboards that merely repackage platform data can amplify inaccuracies. For example, a recent analysis found that 74% of small businesses run display ads, yet platform-reported ROAS often misleads due to attribution flaws. Agencies that proactively reconcile platform data with backend records can turn reporting into a strategic asset, using recovered time for analysis and recommendations rather than just dashboard delivery.

Researchers compress the data-extraction-to-visual workflow by leveraging pre-built World Bank integrations.
For a strategist or researcher producing 2-3 data-driven deliverables per month, WorldSizer saves approximately 2-4 hours per month by eliminating manual country-ranking spreadsheets and static chart creation. The savings scale with content volume; agencies producing weekly data visualizations may reclaim 4-8 hours monthly per seat.
Yes. WorldSizer is open-source and hosted on GitHub, so technical teams can fork the code, customize the data sources, or embed the visualization into client-facing dashboards or reports. This flexibility allows agencies to create branded or client-specific versions without licensing restrictions.
WorldSizer pulls data from World Bank indicators, which cover economic, demographic, environmental, and development metrics across countries. If your team needs proprietary, real-time, or non-World Bank data, you would need to modify the tool or supplement it with other data sources.
