This radial chart visualizes the on-time performance of USA airlines, displaying average departure and arrival delays. The chart uses two colored lines to represent the departure and arrival data, with a color legend explaining the distinction between the two metrics. The visualization is built with React and D3 v5, using `scaleTime` and `scaleLinear` for the angle and radius scales, `lineRadial` for the plotted lines, and `curveLinearClosed` to close the paths. Data comes from a CSV file of flight performance statistics.

AI-generated description

A radial chart of USA airlines on-time performance.

Things have done:

  • Used a cleaner way to transform the chart to center
  • Learned how to close the line: using d3.curveLinearClosed
  • Used a cleaner way to choose the range for radiusScale: innerRadius, outerRadius, angleAxisOffset
  • Added a colorLegend

Things doing:

  • Adding axes (tick marks and labels) for angle: using pointRadial
  • Making the colorLegend interactive

Things to do:

  • Adding axes (tick marks and labels) for radius
  • Choosing a range for the angle scale that represents some periodic amount of time, like years, months, or weeks.

Adding Axes to the radial chart

This radial chart displays average flight delay times for US airlines across months, using a circular time axis with two overlaid paths for departure and arrival delays. The visualization renders in SVG through React, using D3 v5 APIs including `scaleTime` with a full-circle range, `scaleLinear` for radial distances, and `lineRadial` with `curveLinearClosed` to create closed rings. Grid lines extend from the inner to outer radius at each month tick, with month labels positioned along the outer edge. Data comes from a CSV of airline performance statistics loaded via `d3.csv`.

The draft of radial chart

This radial chart visualizes the average departure delay of USA airlines over time, with dates positioned around the circle’s circumference and delay values mapped outward from the center. The closed path connects daily data points using `d3.lineRadial` with `curveLinearClosed`, rendered in SVG within a React setup. Angle and radius scales are created with `d3.scaleLinear`, and the chart is centered by translating the coordinate system. Data comes from an external CSV file on airline on-time performance. Axes and tick labels are not yet implemented.

First Pass Radial Line Chart

This radial line chart visualizes average departure delays for USA airlines on-time performance data, with the date mapped to angle and delay duration mapped to radius. The chart uses d3.lineRadial with curveNatural to create a smooth spiral-like path, while d3.scaleTime and d3.scaleSqrt handle the angle and radius scales. It marks a first pass toward a full radial visualization, with axes and periodic time ranges yet to be implemented. The React component renders SVG marks, reading data from a CSV of departure delay records.

Fork of The draft of radial chart

This radial chart visualizes average flight delays for USA airlines over time, with date values mapped to angles and delay durations mapped to radius. The React component uses d3-scale’s `scaleLinear` for both scales and renders a closed path via `d3.lineRadial` with `curveLinearClosed` in SVG. Data comes from a CSV of daily departure performance, loaded asynchronously with d3.csv. The chart currently displays the radial path without axis ticks or labels, as noted in the project’s documentation.

First Pass Radial Line Chart

This example shows the first pass at converting a line chart of USA airline on-time performance into a radial layout. Using React and D3 v5, it maps date values to angles via `scaleTime` and delay averages to radii through `scaleSqrt`, then draws the path with `d3.lineRadial` and `curveNatural`. The data comes from a CSV of daily departure delays, rendered as an SVG with no axes or tick labels yet.

On-time performance of the top-5 busiest airports in USA

This radial chart shows the on-time performance of the top-5 busiest US airports by plotting average departure delay across dates in a circular layout. Each airport forms a closed line polygon using `d3.lineRadial` with `curveLinearClosed`, colored by a categorical scale. An interactive color legend highlights one airport at a time, fading others via opacity. The visualization uses React for component structure, D3 v5 scales (`scaleTime`, `scaleLinear`, `scaleOrdinal`), and `pointRadial` for angle axis ticks, with data loaded from a CSV of airline performance metrics.

Untitled

A radial line chart displays flight delay trends over time, with a single black path tracing data points around a circular layout. Built with React and D3 v5, the visualization uses `d3.lineRadial` with `curveNatural` interpolation to map departure mean values to radius and date values to angle. The chart is currently a work-in-progress, lacking proper axis ticks and labels, and the angle scale has not yet been configured to represent periodic time intervals like months or years. Data comes from USA airline on-time performance records.

[test] On-time performance of top-5 busiest airports in USA

This radial chart shows the on-time performance of the five busiest US airports, with each colored ring representing an airport’s average departure delay over time. The chart uses D3’s `scaleTime` for the angular axis and `scaleLinear` for the radial axis, with `lineRadial` and `curveLinearClosed` to draw the closed paths. An interactive color legend, built in React, filters and highlights each airport’s trajectory on hover. Data is loaded from a CSV file using D3’s `csv` parsing.
