This multi-line chart displays monthly flight delay counts for four delay categories—carrier, late aircraft, national aviation system, and weather—across airports. It loads CSV data from a GitHub gist using `d3.csv`, then renders paths via `d3.line` with a `d3.scaleBand` x-axis and `d3.scaleLinear` y-axis. Color-coded lines and a manual legend distinguish categories, while axes are generated with `d3.axisBottom` and `d3.axisLeft`. The SVG output uses D3 v6 with the d3-legend library.

A7-Multi-Line Chart in D3

This multi-line chart visualizes flight delays by cause—Carrier, Late Aircraft, National Aviation System, and Weather—across months for a single year. It uses D3 v6 with SVG rendering, loading CSV data from a GitHub gist. The code employs `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.line` to generate paths for each delay category, with a custom legend and axes drawn using `d3.axisBottom` and `d3.axisLeft`.

A7 Multi-Line Chart

This multi-line chart visualizes average annual flight delays across four airline categories using CSV data from a GitHub-hosted airlines dataset. The visualization employs D3.js v7 with SVG rendering, displaying four distinct colored lines with interactive circle markers. The chart uses d3.scaleLinear, d3.line, and d3.axisBottom, while implementing hover-based tooltips to reveal specific year and delay values. ColorBrewer provides the categorical color scheme for distinguishing between airline groups.

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.

A7 - Multi Line Chart

This multi-line chart displays the yearly number of delayed flights for four airports—IAD, DCA, SFO, and LAX—from 2003 to 2016. It uses `d3.csv` to load the data, `d3.scaleLinear` for the x and y axes, and a `d3.line` generator to draw each line. The code groups data by `Airport.Code` with `d3.group`, colors lines via a `d3.scaleOrdinal`, and renders an SVG with an axis, title, and a `d3.legendColor` legend. Y-axis values reach up to roughly 52,000 delayed flights per year.

A7 Small Multiples Lines chart

This small multiples line chart displays yearly average carrier delay counts for multiple airports, with each airport shown in its own grid cell using a shared y-axis scale. The visualization is built with D3 v6 and renders as SVG, using `d3.csv` to load data, `d3.groups` to nest records by airport and year, and `d3.mean` to aggregate delay values. Each chart includes axes via `d3.axisBottom` and `d3.axisLeft`, a line generated with `d3.line` and `curveMonotoneX`, and hover tooltips triggered by mouse events on data circles.

Fork of Assignment 5: line chart with D3

This interactive line chart visualizes monthly airline delay statistics from 2003 to 2016, comparing carrier delays, late aircraft delays, and national aviation system delays. Users can filter by year range and toggle delay categories, with hover tooltips and brush zooming for detailed exploration. Built with D3.js v7, the visualization uses d3.line, d3.axisBottom, d3.axisLeft, and d3.brush to render SVG paths, axes, and interactive selection. Data is loaded from a CSV file and processed as time-series values, with animated transitions when filters change.

Assignment 5: line chart with D3

This line chart visualizes monthly airline delay counts from June 2003 to July 2016, comparing three delay types: Carrier, Late Aircraft, and National Aviation System delays. The chart uses a time scale for the x-axis spanning over 13 years, with data points horizontally offset within each month to reduce overlap. Built with D3 v7, it loads CSV data via `d3.csv`, parses dates with `d3.timeParse`, and renders SVG paths using `d3.line` with monotone curve interpolation. Interactive tooltips appear on mouseover, and axes use `d3.axisBottom` with custom month formatting.

A7 Small Multiples Lines chart

This heatmap visualizes carrier delay counts across months and years for U.S. airlines, using color intensity to show delay severity (from light to dark blue). Built with D3 v7, it maps data to a filled grid of SVG rectangles, with year and month on the axes and hover tooltips for exact values. It includes a linear color legend and uses scales from `d3.scaleBand` and `d3.scaleLinear`, while the data comes from a CSV hosted on GitHub.
