World GDP 2025 – Bubble Map Visualization

To better understand the global economy, I created a Map Visualization in Microsoft Power BI using the 2025 GDP by Country dataset. This visualization displays each country on a world map with bubbles representing its GDP value.

The bubble size is determined by the country's Gross Domestic Product (GDP) in 2025. Countries with larger GDP values appear with larger bubbles, while countries with smaller GDP values appear with smaller bubbles. This makes it easy to compare the economic size of different countries at a glance.

For example:

The United States has one of the largest bubbles because it has one of the world's highest GDP values.
China also appears with a large bubble due to its strong economy.
Countries with smaller economies are represented by smaller bubbles.

This visualization helps users:

Compare the GDP of countries around the world.
Identify the largest economies in 2025.
Understand the global distribution of economic activity.
Analyze regional economic differences using an interactive map.

Power BI Configuration

To create this map, I configured the visualization as follows:

To create this map visualization, I configured the fields as follows:

Location: City
Bubble Size: GDP (2025)

Power BI automatically identified the geographic locations of the cities and plotted them on the world map. The GDP (2025) field was assigned to the Bubble Size, so cities with higher GDP values are displayed with larger bubbles, while cities with lower GDP values appear with smaller bubbles.

Gold and Silver Percentage Analysis Using Ribbon Chart

After importing the Gold and Silver dataset into Power BI, I created a Ribbon Chart to compare the yearly percentage changes in gold and silver prices. This visualization helps identify which metal performed better over different years and how their percentage changes varied over time.

In this report:

The X-axis represents the Year.
The Y-axis represents the Percentage Change (%) in gold and silver prices.
The Dark Blue Ribbon represents the Gold Change Percentage.
The Light Blue Ribbon represents the Silver Change Percentage.

The Ribbon Chart clearly shows both positive and negative price movements. Values above zero indicate an increase in price, while values below zero indicate a decrease. During some years, gold recorded higher returns than silver, whereas in other years silver outperformed gold.

This type of visualization makes it easy to:

Compare yearly performance of gold and silver.
Identify years with the highest and lowest returns.
Observe market trends over time.
Analyze fluctuations in precious metal prices.
Compare multiple categories in a single visual.

To create this visualization in Power BI:

Load the Gold and Silver dataset.
Select the Ribbon Chart from the Visualizations pane.
Drag Year into the Axis field.
Drag Gold Change % and Silver Change % into the Values field.
Customize the chart by adding titles, labels, and colors for better readability.
