How do modern platforms support economic data visualization and communication?
Introduction
1. Introduction
Communicating economic findings effectively is a critical step in converting complex quantitative models to evidence for policy choices. Contemporary tools for data visualization and reporting assist in driving the conversion of raw economic data into findings that can be acted upon. In this article, we review the major platforms: Power BI, Tableau, Jupyter Notebooks, RMarkdown, and several of the advanced visualization libraries (e.g., Plotly, Seaborn, and ggplot2), in the context of their usage for economic research and communicating policy.
2. Visualization and Reporting Tools
2.1. Power BI and Tableau
Interactive dashboarding software such as Power BI and Tableau is used by government agencies, financial organizations, and development organizations, and is likely the more familiar visualization tool for examining time series data, spatial data mapping, and KPI tracking, and the exploratory function of those visualization tools lends itself to economic indicators.
Example:
A central bank could use Power BI to visualize the quarterly trends for GDP growth, inflation, and employment across regions
Power BI Use Case:
- Dataset: World Bank Open Data
- Visuals: Line charts to show GDP growth, map visualizations for inflation at a regional level
- Output: Interactive dashboard updated monthly.
Benefits:
- Drag and Drop Interface.
- Ability to connect data from SQL databases, Excel files, and application program interface (APIs).
- Ability to collaborate in real-time.
Recent Use: The Reserve Bank of India (2023) used Power BI to visualize retail inflation trends in its Monthly Economic Report and to forecast uncertainty intervals.
2.2 Jupyter Notebooks and RMarkdown
Jupyter Notebooks (Python) and RMarkdown (R) offer researchers a reproducible way to perform economic research by integrating the code, outputs, and narrative in one document. This format is well-suited to researchers who work with academic publishing, preparing policy or working papers, or looking to increase methodological transparency.
Example:
A research economist might use Jupyter to fit an ARIMA model to a series on unemployment rates and produce a visual forecast of those unemployment rate projections.
Benefits:
- Transparency and reproducibility
- Integrated code and documents
- GitHub integration makes collaborating easy for others
Recent Use: The IMF (2022) prepared its most recent Global Financial Stability Report with interactive code-based appendices developed in Jupyter, allowing for transparency and replicability.
2.3 Plotly, Seaborn, and ggplot2
Software libraries (for R and Python) like Plotly (Python/R), Seaborn (Python), and ggplot2 (R) provide the ability to produce well-designed, customizable plots for academic journals and government policy mandates.
- Plotly (Python)
Plotly can create interactive visualizations that can be embedded into webpages and dashboards.
- Seaborn (Python)
Seaborn is good for any statistical plot, e.g., distribution plots, regression lines, and heatmaps.
- ggplot2 (R)
ggplot2 is the gold standard in R to produce a publication-quality plot, which is built on “the grammar of graphics.”
Recent Use:
- The OECD (2024) used Plotly for the interactive macroeconomic scenario visualizations for its Economic Outlook.
- Seaborn was used by a 2023 Harvard Kennedy School report to visualize regression diagnostics for a model of inequality.
- ggplot2 is still the most cited R visualization tool in economics journals( Scopus, 2023).
3. Integration of Visualization with Economic Research
Case of Combined Use:
If an academic research team investigated trends in the labor market post-COVID, the team might use the following:
- Jupyter to conduct panel regressions
- Plotly to visualize state-level unemployment trends
- Tableau to present findings to policy advisors
There could be less dependency on static reports and more tailored data-driven policymakers.

4. Conclusion
Today’s visualization platforms have revolutionized the way that economists disseminate their research. Power BI, Tableau, Jupyter, RMarkdown, and libraries such as Plotly, Seaborn, and ggplot2 provide clear, reproducible, and interactive visual experiences. These visualization platforms help to develop a transparent method of communicating complex models to policymakers, stakeholders, and the broader public, thus improving economists’ communication even further.
