This example visualizes earthquake data from the USGS all-week GeoJSON feed, plotting magnitude against time in a scatter plot. Dots are colored by depth category (shallow, intermediate, deep) using `scaleOrdinal`, with a custom color legend that dims non-hovered categories on mouseover. A `brushX` interaction highlights earthquakes within a selected time range, stroking the brushed marks in black. The chart uses D3’s `scaleLinear` for axes, `axisBottom` and `axisLeft` for ticks, and a ResizeObserver for responsive resizing.

Ver2 Earthquake Scatter Plot

This visualization plots earthquake magnitude against time using data from the USGS all-week GeoJSON feed, with points colored by depth category (shallow, intermediate, deep). The main scatter plot includes hover tooltips showing magnitude, location, time, and depth, while a context view below displays the full dataset with a d3.brushX selection that filters the primary view to a brushed time interval. Built with D3 v7 and React, the visualization uses scaleLinear, scaleOrdinal, and utcFormat to render the charts.

Fork of ver2 Earthquake Scatter Plot

This interactive scatter plot visualizes earthquakes from the past week using USGS GeoJSON data, mapping time on the x-axis and magnitude on the y-axis. Points are color-coded by depth category (shallow, intermediate, deep) via d3.scaleOrdinal. The chart uses d3.scaleTime, d3.scaleLinear, d3.axisLeft, and d3.axisBottom for rendering, with a d3.brushX brush for selecting time intervals and highlighting points with a black stroke. A color legend with hover interactions dims non-matching points using d3 transitions.

Final - Earthquake Scatter Plot

This scatter plot visualizes earthquakes from the past week using USGS GeoJSON data, showing the relationship between earthquake depth and magnitude on a time-based x-axis. The circles are colored by depth category (shallow, intermediate, deep), and hovering over the legend highlights one category while dimming the others. Built with D3 v7, it uses `scaleTime`, `scaleLinear`, `scaleOrdinal`, and `axisLeft`/`axisBottom` to render axes and a custom color legend, with a `ResizeObserver` for responsiveness. The plot reveals that shallow earthquakes span the widest magnitude range, while deep earthquakes all exceed M4.0.

Earthquake Scatter Plot expandable x-scale

This interactive scatter plot visualizes earthquake magnitudes over time, with points colored by depth category (shallow, intermediate, deep) using a D3 ordinal color scale. Users can zoom horizontally via a d3.zoom behavior that rescales the time axis, and hover over the color legend to highlight matching earthquakes. The chart uses d3.scaleTime and d3.scaleLinear for axes, with data loaded from a CSV file containing USGS earthquake records. A brush selection adds black strokes to selected points, though the zoom functionality takes precedence.

Fork of Earthquake Scatter Plot

This visualization displays recent earthquakes from the USGS feed, plotting magnitude over time. The main scatter plot uses color to categorize earthquakes by depth, with a legend that filters points on hover. A smaller context view below shows the same data for overview. The code uses D3's `scaleLinear`, `scaleOrdinal`, and `axisBottom` APIs within a custom `scatterPlot` module, and includes a tooltip showing earthquake details on mouseover.

Earthquake Scatter Plot

This scatter plot visualizes earthquake data from January 2024, showing magnitude over time with points colored by depth category (shallow, intermediate, deep). A color legend allows interactive highlighting by hovering over depth categories, while a brush tool supports time-range selection. The visualization uses D3.js APIs including scaleTime, scaleLinear, scaleOrdinal, brushX, and axis components to render the chart with ResizeObserver for responsive sizing.

Scatter Plot Mag Depth

This interactive scatter plot displays earthquake magnitude against depth using live USGS GeoJSON data for all earthquakes from the past day. Each circle represents a quake, positioned by its depth on the x-axis and magnitude on the y-axis, with hover tooltips revealing the exact values. Built with D3 v4, it uses `d3.json` for data loading, `d3.scaleLinear` for axis ranges, and SVG circle elements with `mouseover` and `mouseout` events to trigger the tooltip’s opacity transitions. The chart includes labeled axes with tick marks to facilitate comparison of seismic activity patterns.

Ver03 of Magnitude of Earthquakes - Added Responsiveness

A responsive scatter plot visualizes earthquake magnitude over time from the past seven days, using a USGS-derived dataset loaded via the `@Ljz2018/earthquake` data module. Circles are colored by depth category—red for shallow, blue for intermediate, and green for deep—through a `d3.scaleOrdinal` color scale. The chart employs `d3.scaleTime` and `d3.scaleLinear` for axes, with layout managed by `observeResize` from `@Ljz2018/axis-labels` to adapt width and height dynamically, while `d3.select` and `.join` handle SVG element updates.
