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 displays population over time by region as multiple colored lines, using an ordinal color scale to distinguish each region. The chart orders the lines by their final population value, creating an intuitive ranking. It uses D3 v5 APIs including `nest()`, `scaleTime()`, `scaleLinear()`, `line()` with `curveBasis`, and `axisBottom`/`axisLeft`. Data is processed from UN population estimate CSVs, melted from wide to long format to generate the time-series paths.

Melting Data for Multiple Lines

This example visualizes population estimates and projections over time by region, with multiple colored lines tracing each region's trajectory from 1950 to 2100. The chart emphasizes final population values by sorting lines in descending order and using a legend that displays region names with corresponding colors. Built with D3 v5, the code employs `scaleTime`, `scaleLinear`, `scaleOrdinal`, `line`, `curveBasis`, `nest`, and `axisBottom`/`axisLeft` to render the SVG. Data is loaded and melted from two CSV files containing UN population estimates and medium variant projections.

Melting Data for Multiple Lines

This visualization displays population over time by region, with each line representing a different area and a color legend identifying them. The chart uses d3.csv to load UN population data, which is then processed using d3.nest to group data by region. The code demonstrates a data-wrangling technique called "melting," transforming wide-format data with columns per year into tidy data with year, name, and population fields. Multiple lines are drawn using d3.line and curveBasis, with d3.scaleTime and d3.scaleLinear handling the axes and d3.scaleOrdinal applying colors.

Melting Data for Multiple Lines

This visualization shows population over time by region, with multiple line paths drawn in a single SVG chart. The lines are grouped by region name and displayed with a categorical color scale, accompanied by a legend. Data comes from UN population estimates and medium variant projections, melted into tidy format with `d3.csv`. The chart uses `d3.scaleTime`, `d3.scaleLinear`, `d3.line`, `d3.axisLeft`, `d3.axisBottom`, `d3.group`, and `d3.scaleOrdinal` to render axes, lines, and legends with SVG.

Melting Data for Multiple Lines

This example visualizes population over time by region using multiple smoothed lines, with a color legend and axis labels. It relies on D3 v5 APIs including `nest()`, `scaleTime`, `scaleLinear`, `scaleOrdinal`, `axisBottom`, `axisLeft`, and `line()`, rendering with SVG. Data is melted from wide to long format using a custom function, combining UN population estimates (1950–2014) with medium-variant projections (2015–2100) loaded via `csv`. Lines are drawn with `curveBasis` and sorted by final population value.

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 example shows population over time by region as multiple lines, with regions sorted by their final population and a color legend on the right. The visualization uses d3.line with curveBasis to generate smooth paths, d3.nest to group data by region, and d3.scaleOrdinal with schemeCategory10 for colors. Data is melted from wide UN population CSV files covering 1950–2100, combining estimates and medium-variant projections.

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.
