A heatmap displays earthquake counts for U.S. states from 2010 to 2015, with color intensity varying by magnitude category. A dropdown menu allows filtering by category range, while hovering over cells reveals exact counts via a tooltip. The visualization uses D3 v5 with SVG rendering, employing `d3.scaleQuantize` for color mapping, `d3.nest` for data grouping, and `d3.csv` to load the dataset.

Earthquakes

This heatmap visualizes earthquake counts across U.S. states from 2010 to 2015, with each cell colored by magnitude category. The view initially filters to the "10 to 99" category, but a dropdown menu lets viewers switch between magnitude ranges. Built with D3 v5, the code uses `d3.scaleBand` for axes, `d3.scaleQuantize` for color mapping, and `d3.nest` for category grouping. SVG rectangles render the data, with tooltips showing exact counts via mouseover and mouseleave events.

Earthquakes

This heatmap visualizes earthquake counts (M3+) across U.S. states from 2010 to 2015, with each cell’s color encoding the annual total via a `d3.scaleQuantize` over nine discrete bins. A dropdown menu lets users filter the display by magnitude category (e.g., “10 to 99”), updating the visible rectangles. Built with D3 v5, the SVG renders axes using `d3.axisBottom` and `d3.axisLeft`, while a tooltip appears on hover to show the exact count. Data is loaded from a CSV with `d3.csv` and processed using `d3.nest` for grouping.

Q4 HeapMap

This heatmap displays earthquake counts across U.S. states for each year from 2010 to 2015, filtered by magnitude category via a dropdown selector. The visualization uses a quantized color scale to encode count values, with tooltips revealing exact numbers on hover. Built with D3 v5, it renders SVG rectangles positioned by band scales for states and years, and updates dynamically through a change event listener. The data is loaded from an external CSV file and grouped using d3.nest.

Q4

This visualization shows earthquake counts by US state from 2010 to 2015, using an interactive heatmap with tiles colored on a yellow-to-dark-red scale. A dropdown menu filters the display by earthquake intensity category, and hovering over a tile reveals the state, year, and exact count via a tooltip. The code transforms the wide CSV data into long format, then uses d3.scaleBand for axes, d3.scaleLinear for color, and d3.nest to group data by category. The SVG rendering includes an animated legend, and the visualization is built with React and D3 v5.

Untitled

This example visualizes earthquake data across U.S. states from 2010 to 2015, using a heatmap-like grid where each tile’s color intensity represents the recorded count, with categories grouping states by magnitude ranges. The visualization uses D3.js v3 to render SVG rectangles, with a time scale for the x-axis, a linear scale for the y-axis, and a color scale mapping counts to shades of steelblue. It reads from a CSV file and includes a legend and axes to clarify the count values and date range.

Untitled

A stacked bar chart displays earthquake counts by magnitude range for individual U.S. states across two years. A dropdown menu lets viewers switch between 2017 and 2018, triggering a smooth 750-millisecond transition that updates bar heights, positions, and axis scales. The visualization uses D3 v5 with SVG rendering, employing d3.stack, d3.scaleBand, d3.scaleLinear, and d3.scaleOrdinal to map the year, state, and three magnitude categories from a CSV file. Total counts appear as text labels above each bar.

yi xiao heatmap

This heatmap visualizes earthquake occurrences across U.S. states by year, with color intensity representing the number of earthquakes per state-year combination. The x-axis is sorted by total earthquake count, while the y-axis orders years chronologically. Built with Vega-Lite and D3, it uses a `rect` mark with a red color scale and tooltips revealing exact values. Data comes from a CSV file fetched via D3’s `csv` function, then transformed from wide to long format before being passed to Vega-Lite’s encoding. The visualization is rendered as SVG with a custom configuration for improved readability.

Earthquake Map

This map shows earthquake locations across the United States, with each quake colored by magnitude range from green (0-1.0) to red (3.0-4.0). The visualization uses d3.geoPath and d3.geoAlbersUsa to project USGS earthquake feed data onto state boundaries from a TopoJSON file, with d3.legendColor providing the magnitude legend. Separate SVG layers render quakes for each magnitude bin, and text annotations display counts per category.
