In our interactive educational platform, we’ve strategically emphasized the global map as a central feature, allocating significant screen space and employing a unique color scheme to capture users’ attention. This design choice guides users from comparative analysis tools toward the map and an intuitive list interface, where they can seamlessly navigate to specific continents or countries, or explore options directly from the list. Our decision to maintain a prominent map enhanced with various national flags serves the dual purpose of facilitating data search and comparison, while also enriching students’ geographical knowledge.

To visually organize the information, we’ve employed identity channels, distinguishing continents by hues and countries by saturation levels, to create a clear and accessible user interface. The comparison tool has been thoughtfully limited to six countries at a time, utilizing saturation to effectively differentiate each selection and ensure clarity in comparison. A diverse palette of hues aids in distinguishing continents, enhancing the application’s overall user-friendliness.

The platform incorporates bar charts and graphs to present data, with bar charts organized alphabetically for consistent comparison across different visualizations. We’ve enriched these visual aids with direct value indicators and emojis to convey the status clearly and engagingly.

In line with the ten guidelines for effective data visualization proposed by Kelleher and Wagener, our presentation of graphs and data prioritizes clarity and accessibility. Additional features, like pupil charts, are introduced to further enrich the learning experience.

To aid comprehension, each data visualization is accompanied by an informational popup, offering deeper insights into the depicted statistics. We’ve integrated multimedia resources, such as explanatory videos, to illustrate the real-world implications of poverty and showcase global living conditions, providing a more nuanced understanding of the data.
