This histogram displays the average Air Quality Index (AQI) for each month, derived from ozone data collected across the United States. The visualization uses d3.bin with timeMonths thresholds to group daily measurements into monthly bins, then calculates the mean AQI per bin via d3.mean. The resulting bar chart is rendered as SVG elements through React components, with d3.scaleTime and d3.scaleLinear mapping the time and AQI values. The data is loaded asynchronously from a CSV file using d3.csv, and the bars include tooltips showing each monthly average.

histogram graph for map

This visualization displays U.S. ozone AQI data over time, using a histogram to show monthly average AQI values. The chart reveals how air quality varies across different months. Built with React and D3 v5, it uses `scaleTime` and `scaleLinear` to define axes, `d3.histogram` with `timeMonths` thresholds to bin data, and `mean` to calculate aggregate values. The data is loaded from a CSV file, and the resulting bars are rendered as SVG rectangles with mouseover tooltips showing the average AQI for each bin.

AQI in America with Histogram

This example combines a choropleth map of U.S. states with a histogram of air quality index (AQI) values over time. The map uses d3.geoAlbersUsa projection and d3.geoPath to draw state boundaries, with circles positioned by latitude and longitude and colored by a d3.scaleQuantile. The histogram below aggregates AQI readings by month using d3.histogram and d3.timeMonths, computing monthly means. Both visualizations are rendered as SVG within a React component, using data from a CSV file of ozone measurements.

Fork of map with aqi data with histogram

This interactive visualization combines a map of U.S. states with a time-based histogram of air quality index (AQI) values. The map shows data points as blue circles, with radius scaled by AQI using a square-root transform. A separate histogram displays the monthly average AQI over time, binned by month. The visualization uses React with D3 v5 APIs, including `d3.geoAlbersUsa` and `d3.geoPath` for map projection and rendering, and `d3.histogram` with `timeMonths` for binning. Data is loaded from a CSV file containing ozone samples with geographic coordinates and dates.

AQI Data in America in 2021 with Histogram and Brushing

This interactive visualization displays Air Quality Index (AQI) data across the United States in 2021, combining a bubble map with a linked histogram. Users can brush over the time-series histogram to filter which data points appear on the map. The map uses d3.geoAlbersUsa and d3.geoPath to render state boundaries, while colored circles indicate AQI values using d3.scaleQuantile. The histogram is built with d3.bin and d3.brushX, with data loaded from a CSV file containing ozone measurements.

Fork of AQI Data in America in 2021 with Histogram and Brushing

This visualization displays daily Air Quality Index (AQI) readings across the United States in 2021, combining a geographic scatterplot with a synchronized time-series histogram. Users can brush over the histogram to filter the map’s colored circles by date, with color intensity reflecting AQI levels. The map uses `d3.geoAlbersUsa` and `d3.geoPath` to render state boundaries, while the histogram employs `d3.bin`, `d3.scaleTime`, and `d3.brushX` for interactive selection. Data is loaded via `d3.csv` from a GitHub-hosted dataset, and React manages component state for the brushing extent.

AQI data in America over histogram

This visualization maps Air Quality Index (AQI) data across the United States, displaying each monitoring site as a circle sized proportionally to its AQI value. The map uses a `geoAlbersUsa` projection and `geoPath` to render state boundaries from TopoJSON, while circles are scaled with `scaleSqrt` on a dataset from a CSV file. The React-based interface integrates D3 v5 for data loading and map rendering, with SVG elements providing a clear, interactive view of regional air quality variations.

Json AQI Data in America with Histogram and Brushing

This interactive visualization displays US Environmental Protection Agency Air Quality Index (AQI) readings for ozone monitoring sites, overlaid as colored circles on a geographic map of the United States. The map uses d3.geoAlbersUsa with d3.geoPath, and each circle’s color reflects its AQI value via a d3.scaleQuantile. A brushing histogram at the bottom, built with d3.brushX and d3.bin, filters the map’s circles by date range, with the time series generated using d3.scaleTime and d3.timeMonths. The application is built in React with D3 v5, rendering all elements as SVG.

Fork of Fork of AQI Data in America by State

This visualization combines a choropleth map of average AQI values by U.S. state with a linked time-series histogram. The map uses d3.geoPath and d3.geoAlbersUsa to render state boundaries, with colors assigned via d3.scaleQuantile. A brush on the histogram filters the map to show only data within a selected date range. The histogram bins daily AQI readings by month using d3.histogram and displays the mean value per bin. React manages the state and rendering, with data loaded from a CSV file.
