Forked from Loading Data

This example loads and displays monthly average atmospheric CO₂ measurements from the NOAA Global Monitoring Laboratory at Mauna Loa. It strips comment lines from the CSV, parses the data, and shows a proof-of-life summary with the first six rows in a styled HTML container, including a row count. The visualization uses `d3.csvParse` to handle the data and `d3.select` to target the container element, with the D3 v7 library loaded via a CDN.

AI-generated description

Dataset B — Mauna Loa CO₂ Monthly (NOAA GML)

Source: NOAA Global Monitoring Laboratory — Mauna Loa monthly mean CO₂
What it is: Monthly average atmospheric CO₂ at Mauna Loa (1958–present) with columns for average, interpolated, trend, and number of days.

Columns & attribute types (VAD):

  • year — time (ordered)
  • month (1–12) — ordered (cyclic)
  • decimal_date — quantitative (continuous)
  • average (ppm) — quantitative
  • interpolated (ppm) — quantitative
  • trend (ppm) — quantitative
  • days — quantitative (count)

Notes: The original CSV includes comment lines starting with #. The code strips those before parsing.

d3-line-chart

This example visualizes monthly average atmospheric CO₂ concentrations from the Mauna Loa dataset, shown as a scatter plot with a connecting line over time. The chart loads a CSV file using `d3.csvParse`, parses dates with `d3.timeParse`, and renders points and a line using `d3.line`, `d3.scaleTime`, and `d3.scaleLinear`. Custom axes are drawn with `d3.axisLeft` and `d3.axisBottom`, styled with a dark background and colored points.

Keeling with D3 A

This visualization shows the average atmospheric CO2 concentration at Mauna Loa Observatory for each year, plotted as a filled line chart. The chart displays the data on a Cartesian coordinate system using the Chart.js library, with years on the x-axis and CO2 concentration in parts per million (ppm) on the y-axis. The server, built with Express, parses the provided CSV file via the `fs` and `path` modules, calculates annual averages from the monthly readings, and exposes the processed data through a `/api/co2-data` endpoint. The frontend fetches this JSON data and renders the chart on an HTML canvas element. The underlying data originates from the Scripps CO2 Program's in situ air measurements.

Fork of line Chart with d3.js

This example visualizes the monthly average atmospheric CO₂ concentration from the Mauna Loa dataset, spanning from 1958 onward. It renders a line chart on a dark background, with individual data points drawn as small, randomly colored circles, alongside a connecting line. The chart uses d3’s `scaleTime` and `scaleLinear` to map the date and average value to the plot area, with custom axis labels. Data is loaded from a local CSV file and parsed using d3’s `csvParse` and `timeParse`.

CV: Line Chart

This example shows the monthly rise in atmospheric CO₂ levels at Mauna Loa from 1958 onward. A single black line traces the seasonal fluctuations and overall upward trend across the time series. Built with React and D3 v7, it loads data from a CSV file, uses `scaleTime` and `scaleLinear` for the axes, and renders the path using `d3.line`. The visualization also includes axis labels and handles missing data points through a custom `lineDefinedValue` filter.

Fork of Keeling Curve

This visualization reproduces the Keeling Curve, plotting the monthly average atmospheric CO₂ concentration measured at Mauna Loa from 1958 onward. It shows the well-known upward trend with seasonal oscillations. The D3.js code loads data from a CSV file provided by NOAA’s Global Monitoring Laboratory. It uses `d3.line` to generate the path, `d3.scaleTime` for the x-axis, and `d3.timeParse` to convert the year and month strings into JavaScript `Date` objects.

Keeling Curve

This visualization displays the Keeling Curve, showing monthly average atmospheric CO₂ concentration from Mauna Loa from 1958 onward. The line chart reveals both the seasonal oscillations and the steady upward trend in carbon dioxide levels over time. It uses D3 v7’s `scaleTime`, `scaleLinear`, and `line` generators for the chart, with custom axis and label functions. Data is loaded from a CSV file, parsed with `csvParse`, and dates are converted using `timeParse` before being rendered as an SVG path.

keeling dataset with D3

This visualization displays monthly CO2 concentration measurements from the Keeling dataset as a smooth line chart, with years on the x-axis and CO2 concentration in parts per million on the y-axis. It uses d3.csv for data loading, d3.scaleLinear for axis scaling, and d3.line with curveMonotoneX to draw the trend. The SVG rendering includes axis labels, a steelblue stroke, and a loading state. Data is sourced from a GitHub gist containing the Mauna Loa measurements.

Line Chart with React & D3

This line chart displays monthly atmospheric CO2 concentrations from the Mauna Loa Observatory dataset, with time on the x-axis and CO2 in parts per million on the y-axis. The visualization uses React hooks (useState, useEffect) to load and parse CSV data, while D3 v7 functions like scaleTime, scaleLinear, line with curveMonotoneX, and axisBottom render the chart elements. The line gracefully skips missing data points using the defined accessor in d3.line. Axis labels are added via selection joins in D3.
