This example displays CO2 emissions by country, plotting profit against sub-category over time, with each region represented by a distinct colored line. The visualization uses D3 v5 within a Vue framework, rendering to SVG. It employs `d3.line` with `curveBasis`, `d3.nest` to group data by region, and `d3.scaleOrdinal` with `schemeCategory10` for coloring. Axis labels and legends are added via `d3.axisLeft`, `d3.axisBottom`, and a custom `colorLegend` function, based on sample data from annualco2.csv.

Line Chart with Multiple Lines

This line chart displays per-capita CO2 emissions from 1987 to 2017 for ten countries, with each colored line representing a nation and a legend on the right. The data is loaded from `annualco2.csv` and rendered as SVG paths using D3 v5’s `line` generator with `curveBasis` smoothing. Axes are drawn with `axisBottom` and `axisLeft`, while `scaleTime` and `scaleLinear` map years and emission values. A custom `colorLegend` component and `scaleOrdinal` with `schemeCategory10` assign distinct colors to each country.

Line Chart with Multiple Lines

This line chart shows annual CO2 emissions (in million tonnes) for multiple countries over time, with each country represented as a separate colored line. The data comes from the Data Canvas - Sense Your City dataset, displayed as an SVG using D3 v5. The visualization uses d3.nest to group data by country, d3.scaleTime and d3.scaleLinear for axes, and d3.line with curveBasis for smooth paths. A color legend lists all countries alongside the chart.

Line Chart with Multiple Lines

This line chart displays annual carbon dioxide emissions per capita for the top 10 countries, using multi-color lines to compare trends over time. The visualization reads data from a CSV file and renders it as SVG, with each line representing a country, a color legend for identification, and labeled axes for year and emissions. The implementation uses D3 v5 APIs including `d3.csv`, `d3.line`, `d3.scaleTime`, `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.nest`. A custom `colorLegend` function generates the legend, and gridlines and axis labels are styled for clarity.

Line chart with multiple lines

This visualization shows profit trends across product sub-categories over time, with multiple colored lines representing different states and a legend that filters lines by click. The chart uses d3.csv for data loading, d3.nest to group data by state, d3.scaleLinear for both axes, and d3.line with curveBasis for smooth line paths. A colorLegend component (built with D3 selections) enables interactive highlighting by dimming non-selected states. The SVG rendering includes axes with d3.axisLeft and d3.axisBottom, while the data comes from a CSV file with order details.

Line Chart with Multiple Lines

This line chart shows the annual CO2 emissions per capita for the top ten countries from 1987 to 2017, with each country represented by a distinct colored line and a corresponding legend. The visualization uses D3 v5 APIs such as `scaleTime`, `scaleLinear`, `scaleOrdinal`, `line`, and `curveBasis` to render smooth paths in SVG. Data is loaded from a CSV file, and the chart includes axes, grid lines, and a title.

Line Chart with Multiple Lines

This line chart compares profit by sub-category for different customer segments and regions. It shows multiple colored lines, each representing a region, plotted across sub-categories with profit values on the y-axis. The visualization uses D3 v5 APIs including `scaleLinear`, `scaleOrdinal`, `nest`, `line`, and `curveBasis` to aggregate and smooth the data. A color legend, built with `colorLegend`, identifies each region. The data, sourced from Data Canvas - Sense Your City, is loaded from a CSV and rendered as an SVG.

MULTILINE CHART

This example shows how profit evolved over time for different regions using a multiline chart. The visualization uses d3.line with curveBasis to generate smooth paths, and d3.scaleTime and d3.scaleLinear for the axes. Data is loaded from a CSV file and nested by region using d3.nest. A custom color legend is rendered alongside the chart, and the SVG display includes axis labels and a title.

D3 - Multi-Line Chart

This multi-line chart displays carbon dioxide emissions per country from 1970 to 1979, using four distinct colored lines with circular data points. The visualization loads CSV data from a GitHub gist and renders an SVG with a light gray background panel, axis labels, and a title. It uses d3.csv for data loading, d3.line to construct the paths, and d3.axisBottom and d3.axisLeft for the axes. Interactive tooltips appear on mouseover, showing the emission value for the hovered point, with circles enlarging to indicate selection. The chart also incorporates colorbrewer colors and the d3-legend library.
