This example shows the number of delayed flights for 29 major U.S. airports, sorted from most to least delays, with each bar colored on a diverging purple-orange scale centered on the median value. The visualization uses d3.csv to load the data and d3.scaleBand, d3.scaleLinear, and d3.scaleSequential with the interpolatePuOr interpolator to map delays to bar height and color. Bars are rendered as SVG rect elements, and a color legend is generated via the d3-legend library’s legendColor function, with axes and labels added using d3.axisBottom and d3.axisLeft.

A6: Sequential Bar Chart

This example shows the number of delayed flights for each US airport, with bars colored on a blue sequential scale to highlight the magnitude of delays. A vertical bar chart plots airport codes on the x-axis and delayed flight counts on the y-axis, with higher values rendered in darker blues. The visualization is built with D3 v6, using `d3.scaleBand` for the categorical axis, `d3.scaleLinear` for the numeric range, and `d3.scaleSequential` with `d3.interpolateBlues` for color encoding. Data is loaded from a CSV file via `d3.csv`, and a color legend is added using the `d3-legend` library with threshold labels.

A4 - Bar Chart in D3

This bar chart visualizes the number of delayed flights for various airports using data from a CSV file of airline statistics. Rendered using SVG, the visualization uses D3.js scales and axes to map airport codes along the x-axis and delay counts along the y-axis. Each bar is colored turquoise, with values labeled above the bars. The chart highlights comparative delays across airports, allowing viewers to quickly identify those with higher congestion or operational issues. The implementation leverages d3.select, d3.csv, d3.scaleBand, and d3.scaleLinear to structure the data and layout.

bar chart

A grouped bar chart visualizes airline delay totals across six airports for each month of the year, with each airport’s monthly value rendered as a distinct bar. The chart uses D3 v7’s `d3.scaleBand` for the month categories on the x-axis and `d3.scaleLinear` for the delay magnitude on the y-axis, both fed by an external CSV file. SVG `rect` elements represent the bars, while `d3.axisBottom` and `d3.axisLeft` generate the corresponding axes. The data originates from the `airline.csv` file, containing airport, month, and total delay values.

Fork of Assignment 6: Diverging Bar Chart with Color Legend

This visualization shows a diverging bar chart of carrier delays for various airports, with each bar colored by its deviation from the average delay. The chart uses a D3 v7 SVG rendering with a ColorBrewer RdBu diverging color scale applied through `d3.scaleDiverging`. A color legend is generated using the `d3.legend` library, displaying the deviation values. Data comes from a remote CSV file, where delays are parsed and deviations computed via `d3.mean`. Horizontal bars extend left or right from a zero baseline, and both axes are rendered with D3’s `d3.axisLeft` and `d3.axisBottom`.

Assignment 4: Bar Chart with D3

This bar chart visualizes the top 10 airports ranked by total carrier delay minutes, using a logarithmic y-scale to accommodate wide value ranges. The visualization loads CSV data via `d3.csv`, aggregates values with `d3.rollup`, and renders SVG bars using `d3.scaleLog` and `d3.scaleBand`. Interactive tooltips appear on hover, displaying the airport code and delay count, while axes are generated with `d3.axisBottom` and `d3.axisLeft`.

A7-Small Multiples Chart in D3

This example presents a small multiples chart of flight delays by airport, visualizing four delay categories—Carrier, Late Aircraft, National Aviation System, and Weather—across monthly data. It uses d3.csv to load data and d3.line to render each series as a separate line graph, with d3.axisBottom and d3.axisLeft providing tick marks and labels. The chart employs d3.scaleOrdinal with d3.schemeCategory10 to color-code each category and d3.legend from d3-legend to display a legend, arranging the four plots in a 2x2 grid within an SVG.

Bar Chart for USA Flights Delay _ React & D3

This interactive bar chart visualizes the average departure delay for USA flights by month. Each horizontal purple bar represents a month, with its length proportionally reflecting the mean delay in minutes. The visualization is built using React and D3.js (with `scaleBand` for the y-axis and `scaleLinear` for the x-axis), rendering as an SVG. Data is loaded from a remote CSV file, pre-processed to calculate monthly averages, and displayed with axis ticks and labels.

Fork of Assignment 6: Bar Chart with Color Legend

This example shows carrier delay counts for various airports in a bar chart, with each bar colored on a blue sequential scale to encode delay severity. The visualization loads data from a remote CSV file using `d3.csv`, then renders an SVG with `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis. It uses ColorBrewer’s Blues palette via `d3.interpolateRgbBasis` to create the color mapping, and the `d3-legend` library’s `d3.legendColor` to display a matching color legend. Axis labels are rotated with SVG attributes, and bars use `d3.axisBottom` for x-axis ticks.
