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.

AI-generated description

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

Iterated from last week's visualization.

What's new?

  1. Added latitude and longitude to data.
  2. Added interactive world map with circles showing where earthquakes occured, and the radius of circle shows richter of earthquake.
  3. Changed the layout. Now all visualizations are in the same page.

Todo:

  1. Add tooltips.
  2. Change buttons to menu.

Bar plot:

X-axis: region that earthquake occured.

Y-axis: Deaths in earthquake.

World map:

Circle: positions where earthquake occured.

Radius: richter 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).

Interactive Visualization (Two Menus) - Earthquake Data

This interactive visualization presents earthquake data from the 20th century through a bar plot and a world map. Two dropdown menus allow users to filter the data by start and end year, updating both the bar chart of regional death tolls and the map’s earthquake locations. The map uses `d3.geoPath` with a Mercator projection to render country outlines, while circle radii encode the Richter scale magnitude. The bar chart employs `d3.scaleBand` and `d3.scaleLinear` for axes, with tooltips providing country names on map hover. Visualizations render in SVG with smooth transitions.

Fork of Interactive Visualization (Two Menus) - Earthquake Data

This interactive visualization displays earthquake data from the 20th century using a bar plot and a world map. The bar plot shows total deaths by region, while the map uses circle radius to represent earthquake magnitude on the Richter scale. Users select start and end years from two drop-down menus, which updates both visualizations. The code uses D3 v7 with SVG rendering, including d3.geoMercator projection, d3.scaleLinear and d3.scaleBand scales, and tooltip interactions for the map. Data comes from a GeoJSON world map and an external earthquake dataset.

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.

Fork of Visualization (Two Menus) - Earthquake Data

This interactive visualization pairs a bar chart with a world map to explore earthquake deaths and magnitudes. Two dropdown menus filter the data by start and end year, with the bar chart showing total deaths per region and the map displaying earthquake locations scaled by Richter magnitude. The visualization uses D3.js v7 with d3.geonear and d3.geoPath for the map projection, d3.scaleBand and d3.scaleLinear for axes, and animated transitions for tooltips and updates. It loads world geography from a GeoJSON file and earthquake data from a GitHub gist, with a legend added to the map.

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.

Interactive Visualization (Brush) - Earthquake Data

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.

Interactive Earthquake Bar Plot

This interactive bar plot displays earthquake deaths across various regions during the 20th century, with buttons filtering the data into 20-year periods. When a user clicks a button, the bars re-sort by death toll and smoothly animate to their new positions via D3's `transition` on the `rect` elements. The code uses `d3.csv` to load the dataset, `d3.scaleBand` and `d3.scaleLinear` for axes, and `d3.axisBottom` and `d3.axisLeft` to render them. The visualization is built with D3 v7 and rendered as SVG.

Fork of Fork of Interactive Visualization (Brush) - Earthquake Data

This interactive dashboard combines a bar chart, a world map, and a scatter plot to explore earthquake data from 2000 to 2021. The bar chart shows the mean yearly earthquake magnitude, while the world map, built with `d3.geoPath` and a Mercator projection, plots earthquake epicenters with circle radii scaled by Richter magnitude. A linked scatter plot uses `d3.select` to display year against magnitude, with point size representing deaths. The map also includes tooltips on hover, and the data for the bar chart is loaded from a CSV file.
