Eight weeks of simulated playoff power rankings are shown as eight colored, semi-transparent lines, one per team, across the x-axis (week) and y-axis (power rank). Hovering over a line thickens it and increases its opacity. Built with D3 v5, it uses `d3.line()`, `d3.nest()`, `d3.scaleOrdinal()`, and a custom legend from `d3.axisLeft()` calls, reading the `data.csv` file. Lines are drawn as SVG paths, and hover effects use D3's `.transition()` for animation.

Making a Multiline Chart 2

A multiline chart displays weekly power scores for eight teams across eight weeks, with a clickable legend highlighting team names and interactive hover effects that thicken lines. The visualization is built with D3 v5, using SVG rendering, `d3.nest()` to group data by team, `d3.line()` for path generation, and `d3.scaleOrdinal` with `d3.schemeCategory10` for colors. It includes axis labels, a dashed baseline, and a filterable legend with custom click handlers.

Multi Line Chart

This multi-line chart displays three data series (A, B, C) over a two-week period in July–August 2019, plotting daily measurement values. Each series is rendered as a distinct colored path with different dash patterns, accompanied by end-of-line labels. The visualization uses D3 v5 with an SVG viewBox for responsive scaling, d3.scaleTime and d3.scaleLinear for axes, d3.line with default curve interpolation for paths, and d3.axisLeft/axisBottom for gridlines. Data comes from an inline CSV file.

CPSC 436V Week 6 - Multiline Chart

This example visualizes one week of temperature readings from cities around the world, plotting each city as a distinct colored line over time. The chart uses d3.scaleTime, d3.scaleLinear, and d3.line with curveBasis to create smooth paths, while d3.nest groups data by city. A color legend, built with a custom colorLegend function, orders entries by each line’s final temperature value. The rendered SVG includes styled axes with gridlines, a title, and axis labels, drawing from a CSV dataset loaded via d3.csv.

Multi-Series Line Chart

Two teams’ cumulative run totals are tracked across twenty overs, with each team rendered as a distinct colored line. The chart uses D3.js v4 to build an SVG scene, mapping overs to the x-axis and runs to the y-axis. The data is drawn from a hardcoded array, and an animated redraw on window resize re-renders the entire visualization. A legend identifies each team, and the code leverages d3.scaleOrdinal, d3.line, and d3.axisBottom to construct the graphic.

Multiline chart

This multiline chart displays profit trends across regions over time, with each line representing a region and colored via a categorical scale. Built with D3 v5, the visualization uses `d3.nest` to group data by region, `d3.line` with `d3.curveBasis` for smooth paths, and custom axis and legend components. The data, sourced from Data Canvas - Sense Your City, is loaded from a CSV and rendered as SVG.

LineChart with Multiple Lines

A multi-line chart displays a week of temperature readings across multiple cities, with each city represented by a distinct colored line and a color legend. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, `line` generator with `curveBasis`, and `nest` to group data by city, while `axisBottom` and `axisLeft` render labeled axes. Data is loaded from a CSV file, and the chart is drawn as SVG with a title and a custom color legend.

Line Chart with Multiple Lines

A multi-line chart shows temperature readings from multiple cities over one week, using color-coded paths to distinguish each city. The visualization includes a custom color legend and interactive mouse tracking that displays tooltips with the exact timestamp and temperature at the cursor position. Built with D3 v5, the code uses `scaleTime`, `scaleLinear`, `scaleOrdinal`, `nest`, `line`, and `curveBasis` to structure the data and render SVG paths. The data comes from a CSV file loaded via `csv`, with axes generated using `axisBottom` and `axisLeft`.

Line Chart with Multiple Lines

A multi-line chart displays a week of temperature readings across multiple cities, with time on the x-axis and temperature on the y-axis. The visualization uses d3.scaleTime, d3.scaleLinear, and d3.scaleOrdinal with a category10 color scheme to encode city identity. Lines are generated with d3.line and a basis curve, while a custom color legend component renders SVG circles and text. Data comes from a CSV file loaded via d3.csv, with axes and gridlines produced by d3.axisBottom and d3.axisLeft.
