This example shows a multi-series line chart comparing daily average temperatures across three US cities—New York, San Francisco, and Austin—over a three-month period from October 2011 through January 2012. The data is loaded from a tab-separated values file using d3.tsv. Each city is encoded as a separate colored line, with the date on the x-axis and temperature in degrees Fahrenheit on the y-axis. The visualization uses d3 v4 with SVG rendering to draw axes, gridlines, and a legend, making seasonal trends and city-to-city differences readily apparent.

Multi-Series Line Chart

This multi-series line chart visualizes daily average temperatures for New York, San Francisco, and Austin over the course of a year, with each city encoded as a colored line. The x-axis represents time using d3.time.scale, while the y-axis uses a linear scale for temperature values. Colors are assigned via d3.scale.category10, and the data is loaded from a TSV file using d3.tsv. The chart applies conventional margins, computes domains with d3.extent, d3.min, and d3.max, and renders axes and lines using d3.svg.axis and d3.svg.line. The visualization compares seasonal temperature patterns across the three cities, highlighting relative warmth and variation throughout the year.

Multi-Series Line Chart

This multi-series line chart displays daily average temperatures for New York, San Francisco, and Austin over one year, loaded from a TSV file via d3.tsv. The visualization uses d3.time.scale for the x-axis, d3.scale.linear for the y-axis, d3.scale.category10 for color encoding, and d3.svg.line with basis interpolation to draw each city’s temperature trend. Axes are rendered with d3.svg.axis, while d3.extent, d3.min, and d3.max compute the domains. City labels appear at the end of each line, and the SVG output uses conventional margins.

Lab3 - Multi-Series Line Chart

This multi-series line chart visualizes daily average temperatures for New York, San Francisco, and Austin over a year, using data loaded from a TSV file via d3.tsv. The x-axis employs a time scale with dates parsed by d3.time.format, while the y-axis uses a linear scale for temperature values. Each city’s temperature series is drawn as a separate colored line using d3.svg.line, with colors assigned from the category10 ordinal scale. The chart computes its x- and y-domains dynamically with d3.extent, d3.min, and d3.max, and uses d3.keys to identify the city columns in the dataset. Conventional margins are applied, and axes are rendered with d3.svg.axis. The visualization compares daily average temperatures across New York, San Francisco, and Austin over one year, highlighting seasonal differences among the three cities.

Multi-Series Line Chart

This multi-series line chart displays daily average temperatures for New York, San Francisco, and Austin over one year, using color to distinguish each city's trend. The visualization encodes dates on the x-axis via `d3.time.scale` and temperatures on the y-axis via `d3.scale.linear`, with `d3.svg.axis` rendering the axes. Data is loaded from a TSV file using `d3.tsv`, and each city’s line is drawn with `d3.svg.line`, colored by `d3.scale.category10`. The chart uses conventional margins and an SVG rendering approach, with city labels placed at the final data point.

Multi-Series Line Chart

This multi-series line chart visualizes daily average temperatures for New York, San Francisco, and Austin over a year, with three colored lines plotted against a time-based x-axis and a temperature y-axis. The visualization is built with D3 v3 and rendered as SVG, using conventional margins. It loads data from a TSV file via d3.tsv and leverages d3.time.format to parse dates, d3.time.scale for the x-position, d3.scale.linear for the y-position, and d3.scale.category10 for color encoding. Domains are computed with d3.extent, d3.min, and d3.max, while column names are derived using d3.keys. Axes are rendered with d3.svg.axis and the lines with d3.svg.line. The chart illustrates seasonal temperature variations across the three cities over a year, with each line distinguished by color.

Multi-Series Line Chart

This visualization displays the daily average temperature for New York, San Francisco, and Austin over a year, with three colored lines allowing direct comparison of seasonal patterns. The chart uses D3 v3 APIs, including `d3.tsv` for data loading, `d3.time.format` for date parsing, `d3.time.scale` for the x-axis, `d3.scale.linear` for the y-axis, and `d3.scale.category10` for color encoding. It renders with SVG, using `d3.svg.axis`, `d3.svg.line`, and `d3.keys` to structure city series from the TSV data.

Multi-Series Line Chart

This multi-series line chart visualizes daily average temperatures for New York, San Francisco, and Austin over a year, with each city represented by a distinct colored line. The visualization uses D3.js with SVG rendering, employing conventional margins and scales: a time scale for dates on the x-axis, a linear scale for temperature on the y-axis, and a categorical color scale for the three series. Data is loaded from a TSV file using d3.tsv, and dates are parsed with d3.time.format. The chart computes its domains using d3.extent, d3.min, and d3.max over the parsed dataset, derives series names dynamically with d3.keys, and renders axes and line paths with d3.svg.axis and d3.svg.line. The example demonstrates a clean, reusable pattern for multi-series time-series data, with a legend distinguishing New York, San Francisco, and Austin.
