This example shows a week of temperature readings from multiple cities as smooth, overlapping line paths, with a color legend matching each line to its city. The chart uses D3 v6 with `scaleTime`, `scaleLinear`, and `scaleOrdinal`, and nests the CSV data by city via `d3.nest`. Lines are generated with `d3.line` and `curveBasis`, while a custom `colorLegend` component renders the legend with SVG circles and text.

Line Chart with Multiple Lines

This line chart displays a week of temperature readings from multiple cities, with each city represented by a colored, smoothed line. The visualization uses D3 v5's `nest()` to group data by city and `scaleTime`/`scaleLinear` for axes. A custom `colorLegend` component renders the categorical color scale, while `axisBottom` and `axisLeft` include gridlines. Data comes from a CSV file loaded via `csv()`, and the SVG rendering applies a multiply blend mode to overlapping lines.

Line Chart with Multiple Lines

This example displays a week of temperature readings for multiple cities, with each city represented by a colored line that conveys its temperature trend over time. A legend identifies the color associated with each city. The visualization uses d3.line with curveBasis for smooth paths, d3.scaleTime and d3.scaleLinear for axes, and d3.nest to group the CSV data by city. d3.scaleOrdinal with schemeCategory10 assigns colors, while custom legend and axis components are built using SVG.

Line Chart with Multiple Lines

This example displays temperature readings from multiple cities over a week, with each city represented by a colored line and a corresponding legend. The chart uses d3.scaleTime, d3.scaleLinear, and d3.scaleOrdinal to map time, temperature, and city names, while d3.line with curveBasis smooths the paths. Data is loaded via d3.csv from an external dataset, and the SVG is rendered with axes, grid lines, and labels styled through CSS.

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

This line chart displays a week of temperature readings from multiple cities around the world, with each city represented by a distinct colored line plotted over time. The visualization uses D3 v6 with SVG rendering, employing `d3.scaleTime`, `d3.scaleLinear`, `d3.line` with `curveBasis`, and `d3.nest` to group data by city. A color legend built with `d3.scaleOrdinal` and `schemeCategory10` identifies each line. The data comes from a CSV file loaded via `d3.csv` and rendered with custom axes, grid lines, and a title.

Line Chart with Multiple Lines

This line chart displays temperature readings from multiple cities over a week, with each city represented by a colored line and a corresponding color legend. The visualization uses d3.csv to load the dataset, d3.nest to group records by city, and d3.line with curveBasis to generate smooth paths. Axes are created with d3.axisBottom and d3.axisLeft, while the ordinal color scale uses d3.schemeCategory10. The chart renders as SVG with grid lines and a simplified custom legend.

Line Chart with Multiple Lines

This line chart displays temperature readings from multiple cities over one week, with each city represented by a distinct colored line and a corresponding color legend. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, and `scaleOrdinal` to map time, temperature, and city categories, while `nest()` groups the data by city and `line()` with `curveBasis` generates smooth paths. Axes are rendered with `axisBottom` and `axisLeft`, and the legend is built using a custom function that appends circles and text. Data originates from the Data Canvas - Sense Your City dataset.

Line Chart with Multiple Lines

This example shows a week of temperature readings for multiple cities, with each city represented as a separate colored line plotted over time. The chart includes a color legend, labeled axes, and a title, with lines sorted by their final temperature values. It uses D3 v5’s `scaleTime`, `scaleLinear`, and `scaleOrdinal` for scales, `line` with `curveBasis` for path generation, and `nest` to group data by city. Temperature data is loaded from a CSV file and rendered as an SVG with axis and legend components.
