This project delivers an interactive data dashboard that visualizes software engineering job postings in the United States in 2024. It consolidates key insights into a single, easy-to-use interface so users can quickly explore the market and understand compensation trends.
Figure 1: Dashboard overview
Figure 2: State-level map view
Highlights of the dashboard:
- Scatter plot: experience-salary analysis across companies with adjustable axes and a drop-down filter.
- Bubble chart: interactive bubble chart where each bubble represents a company with its rating.
- Geographic distribution map: a two-level (nation/state) map of the United States, featuring its user-friendly interactive plays and smooth animation.
- Bidirectional filtering: selecting a state in the map filters the bubble chart to display only companies in that state, and clicking a company bubble triggers a zoom animation to that company's state on the map.
- Tooltip on hover: detailed information about companies and job postings.
The positioning of United States cities on the map view relies on a local copy of the TopoJSON library (v3.0.2). The geographic data, including the latitudes and longitudes of United States cities used in this project, depends on a publicly accessible dataset built from the U.S. Census Bureau.
