Taiwan Earthquake
This visualization analyzes one year of earthquake data from Taiwan’s Central Weather Administration, showing seismic activity on a zoomable Mercator map and an interactive scatterplot. Users can select a year and adjust the x and y axes to explore correlations between magnitude, depth, and other attributes. The map uses d3.geoPath with topojson to render county boundaries, while the scatterplot applies d3.scales and axes. Circles are sized by magnitude and colored by selected categories, with hover tooltips and a legend that updates dynamically.
AI-generated descriptionThe dataset I picked is the earthquake data in Taiwan.
Tasks I want to explore are:
- Where do earthquakes of higher magnitude or depth tend to occur more frequently? In which city or county in Taiwan? In which region of Taiwan?
- Is there any correlation between the magnitude of earthquakes and their focal depth?
- How do the frequency and magnitude of earthquakes vary over time?
The website contains visualizations for other tasks. Please take a look at Tasks 3, 4 and 5. You could interact with the map and scatterplot by choosing the x attribute and y attribute and mouseover the dots in the plot. The heatmap for Task 5 is incomplete.
