Ukraine Regional Response: Needs, Intentions, and Border Crossings

My Tasks:

Data visualization and chart generation.( R + Tableau.)

The charts in IOM’s PowerBI dashboards displayed several limitations, such as:

  • Truncated labels:

  • Only depicting the top 10 (or in some instances, 5 or 7) categories of an indicator due to a lack of space:

  • Visualize the survey data through better and well-designed charts that would be free of constraints (such as only depicting the top 10 categories). 

  • Visualize new indicators from recent quarters that were yet to be added to the dashboard.

Key Tasks and Responsibilities:

Analyzed 2 important survey datasets containing 25000+ observations each.

  1. Data Visualization and Chart Generation:

  •   Created various types of charts to improve the visual representation of data.

  •   Focused on preferred chart types and important indicators to highlight patterns within the data.

  1. Addressing Limitations in Existing Dashboards:

  •   Resolved issues such as truncated labels that hindered data readability.

  •   Expanded the scope beyond the top 10 categories, accommodating a more comprehensive view of indicators.

  1. Introduction of New Chart Types:

  •   Developed and implemented charts like the dumbbell chart to depict before and after scenarios.

  •   Created population pyramid charts to represent demographic distributions effectively.

  •   Designed Likert scale charts for nuanced data presentation.

  4. Visualization of New Indicators:

  •   Incorporated new indicators from recent quarters that were previously not included in the dashboard.

  •   Ensured that the visualizations were free from the constraints of depicting only a limited number of categories.

Development

Created BAN’S for the Dashboard using Svelte+D3

I contributed to the development of two key Svelte components for the dashboard. These components were designed to display Big Aggregate Numbers (BANs) and were integrated using D3.js in a collaborative environment on GitHub.

  • Worked in a collaborative environment on GitHub, ensuring smooth integration and functionality of the components.
  • Engaged in code reviews and iterative improvements, leveraging team feedback to enhance the components’ performance and usability.

Outcome:

The improved visualizations provided a more detailed and comprehensive view of the survey data, enhancing the overall effectiveness of IOM’s PowerBI dashboards. These enhancements allowed for better data interpretation and decision-making processes.
