Forked from Melting data for multiple lines

This visualization shows population trends over time for the world’s regions, with each region drawn as a distinct colored line and accompanied by a color legend. The data is loaded from UN population estimates and medium variant projections, then reshaped from wide to long format using custom logic. D3 v5’s `nest`, `scaleTime`, `scaleLinear`, `scaleOrdinal`, `line`, and axis functions render the SVG line chart. Lines are ordered by their final population value, and gridlines are enhanced with tick marks.

Melting Data for Multiple Lines

This visualization displays population over time by region, with multiple colored lines representing different world regions from 1950 to 2100. The chart uses D3 v5’s `nest()` to group data by region, `scaleTime` and `scaleLinear` for axes, and `line` with `curveBasis` to generate smooth paths. Data comes from UN population estimates and medium variant projections, processed by melting wide-format CSV data into tidy long format. A custom `colorLegend` function renders the categorical color scale, and the visualization includes gridlines, axis labels, and a title.

Melting data for multiple lines

This visualization shows population trends over time for global regions, with each region drawn as a separate colored line and a legend identifying the regions. The data comes from UN population estimates (1950–2014) and medium-variant projections (2015–2100), melted into tidy format. The code uses d3.csv, d3.nest, d3.scaleTime, d3.scaleLinear, d3.scaleOrdinal, d3.line with curveBasis, and d3.axisLeft/axisBottom. A custom colorLegend module renders the legend, while SVG paths with mix-blend-mode multiply display overlapping lines.

Melting Data for Multiple Lines

This visualization shows population over time by region, with multiple colored lines tracing each region’s trajectory from 1950 to 2100. The chart uses a time scale for the x-axis, a linear scale for population, and an ordinal color scale with a custom legend. D3’s `nest()` and `scaleOrdinal` group and color the series, while `d3.line` with `curveBasis` smooths the paths. Data comes from UN population estimates and medium-variant projections, melted into a tidy format for plotting as SVG.

Melting Data for Multiple Lines

This visualization displays population trends over time for various world regions using multiple lines. The chart combines historical estimates from a 2017 UN dataset with medium-variant projections through 2100, showing each region’s population trajectory in a distinct color. The code uses d3.csv to load data, d3.nest to group by region, d3.line with curveBasis for smooth paths, and d3.scaleTime and d3.scaleLinear for axes. A custom colorLegend component renders the categorical scale, while d3.axisLeft and d3.axisBottom create labeled tick marks.

Melting Data for Multiple Lines

This visualization shows population trends over time for regions, displaying multiple lines that trace changes from 1950 to 2100. The data is sourced from UN population estimates and medium variant projections, processed through a melting operation that converts wide-format data into long format. The chart uses D3.js v5 APIs including `scaleTime`, `scaleLinear`, `scaleOrdinal`, `line` with `curveBasis` for smooth paths, and `nest` for grouping by region. An ordinal color scale with `schemeCategory10` assigns colors, while a custom legend shows region names.

Melting Data for Multiple Lines

This visualization shows population trends over time for different global regions, with multiple lines plotted on a time-series chart. The legend and color scale indicate which line corresponds to which region. The code uses d3.csv to load UN population data, d3.nest to group by region, d3.line with curveBasis for smooth paths, and d3.scaleTime and d3.scaleLinear for axes. A custom colorLegend module renders the interactive legend using SVG circles and text.

Melting Data for Multiple Lines

This visualization shows projected population over time by region, with multiple colored lines representing different areas. The line paths are sorted by their final population values, and a categorical color legend identifies each region. The code uses D3 v5’s `nest`, `line`, `scaleTime`, `scaleLinear`, and `scaleOrdinal` APIs. Data is loaded from UN population CSV files and melted from wide to long format in `loadAndProcessData.js`, then rendered as an SVG with axis labels and a legend.

Melting Data for Multiple Lines

This visualization shows population trends over time for global regions, with each region represented as a colored line. The chart uses multiple lines to compare regional population growth from 1950 to 2100, with a color legend on the right side. The code processes United Nations population data by melting it into a tidy format, then uses d3.line with curveBasis to generate smooth paths, d3.nest to group by region, and d3.scaleOrdinal with schemeCategory10 for colors. Axes are rendered using d3.axisLeft and d3.axisBottom, with SVG rendering and custom tick formatting for population values.
