This interactive visualization presents earthquake data from the 19th century through three coordinated views: a bar plot of deaths by region, a world map with circles sized by Richter magnitude, and a scatter plot correlating year, magnitude, and deaths. A brush interaction on the scatter plot filters the year range across all views. The map uses d3.geoMercator projection with d3.geoPath to render country boundaries from a GeoJSON source, includes a magnitude legend, and displays country names via tooltips on mouseover. The charts are built with D3 v7 APIs including scaleBand, scaleLinear, and the join operator.

Data: https://gist.github.com/Junying-Li/72ef4641efd6b4abf371f5d9f4267a56

What's new?

  1. Added scatter plot.
  2. Added brush (select year).
  3. Added legend for world map.
  4. Added tooltips for world map.

Todo:

Bar plot:

X-axis: region that earthquake occured.

Y-axis: Deaths in earthquake.

World map:

Circle: positions where earthquake occured.

Radius: richter of earthquake.

Scatter plot:

X-axis: year.

Y-axis: richter of earthquake.

Radius: deaths of earthquake.

The bar plot shows the deaths caused by earchquakes in mutiple regions in different period of 19 century. The world map shows the positions where earthquakes occured and how strong they were (richter scale). The scatter plot shows richter and deaths of earthquakes in different years.

Interactive Visualization (Brush) - Earthquake Data

This interactive dashboard visualizes earthquake data with three synchronized views: a bar plot of regional death tolls, a world map showing earthquake locations with circle radii scaled by Richter magnitude, and a line chart depicting global deaths by year. The code uses d3.geoPath with a Mercator projection to render the map, while d3.brush enables year selection that updates all views. Hovering over map regions triggers tooltips via mouseover events, and a legend explains the Richter scale. Data is loaded via d3.csv from an external gist URL, with d3.scaleLinear and d3.scaleBand managing the axes.

Fork of Interactive Visualization (Brush) - Earthquake Data

This interactive visualization explores earthquake data from the 19th century through three coordinated views: a bar plot of total deaths by region, a world map with circles sized by Richter magnitude, and a scatter plot relating year, magnitude, and death toll. A brush on the scatter plot filters data across all views, while tooltips display country names on the map alongside a legend for magnitude. The code uses D3 v7 APIs including d3.csv, d3.scaleBand, d3.scaleLinear, d3.geoMercator, d3.geoPath, and d3.brushX to render SVG with animations, sourcing data from a GitHub gist.

Fork of Interactive Visualization (Brush) - Earthquake Data

This visualization presents earthquake data through three linked views: a bar plot of regional death tolls, a world map plotting earthquake locations with circle size encoding Richter magnitude, and a scatter plot relating year, magnitude, and deaths. A brush selection on the scatter plot filters the other views, while map tooltips display location names and a legend explains magnitude scaling. The code uses d3.v7 with `d3.geoMercator` projection, `d3.geoPath` for map rendering, and `d3.scaleBand`/`d3.scaleLinear` for chart axes. Data comes from a GitHub-hosted world GeoJSON and earthquake CSV.

Fork of Interactive Visualization (Brush) - Earthquake Data

This visualization of earthquake data combines a bar plot, world map, and scatter plot to explore regional deaths, epicenter locations with Richter magnitudes, and the relationship between year, magnitude, and casualties. Users can brush on the scatter plot to filter the other views by year. The map uses d3.geoMercator with d3.geoPath to render world geography, while tooltips display country names on hover. All charts are built with d3.v7, rendering as SVG with animation, and the data is loaded from an external CSV source.

Fork of Interactive Visualization (Brush) - Earthquake Data

This visualization combines a bar plot, world map, and scatter plot to explore earthquake data. The bar plot shows total deaths by region, the map displays earthquake locations with circle radius representing Richter scale magnitude, and the scatter plot correlates year with Richter magnitude and death counts. The implementation uses D3 v7 with d3.geoPath for map projection, d3.scaleBand and d3.scaleLinear for axes, and includes interactive brushing, tooltips via mouseover events, and a legend. Data comes from a CSV file referenced in the code.

Visualization (Brush) -NBA

This interactive visualization presents earthquake data through three coordinated views: a bar plot of regional death tolls, a world map showing earthquake locations with circle radii encoding Richter magnitude, and a scatter plot relating year, magnitude, and fatalities. The map uses d3.geoPath with a Mercator projection, includes a legend for magnitude values, and displays country names via a custom tooltip. The bar plot employs d3.scaleBand with axes, while the map’s tooltip and the legend are built using D3 selections. The example also demonstrates d3.json for loading GeoJSON data and integrates d3.v7.

Interactive Visualization (One Menu) - Earthquake Data

This interactive visualization displays earthquake data from 1900 to 1999, combining a world map and a bar chart. The map uses `d3.geoMercator` and `d3.geoPath` to render earthquake locations as circles, with radius representing Richter magnitude. The bar chart aggregates total deaths by region, updating via a dropdown menu that filters data by twenty-year intervals. Both SVG visualizations share the same dataset, loaded from a CSV file, and employ D3 v7’s data-join and transition methods for updates.

Interactive Visualization (button) - Earthquake Data

This interactive visualization displays earthquake deaths by region in a bar plot alongside a world map showing earthquake locations and magnitudes. Users click buttons to filter data across different 20th-century time periods. The bar chart sums deaths per region using d3.csv, d3.filter, and d3.sum, while the map uses d3.geoMercator and d3.geoPath to project earthquake positions as circles sized by Richter scale. Data comes from a CSV containing latitude, longitude, and earthquake details.
