This visualization displays population over time by region, with a multi-line chart that sorts regions by their final population values. The data is melted from wide-format United Nations CSV files into tidy long-form rows using a custom function that iterates over years. The code uses d3.csv, d3.nest, d3.scaleTime, d3.scaleLinear, d3.scaleOrdinal, d3.line with curveBasis, and a custom color legend module. Animated axis labels and a title are rendered as SVG elements.

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 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 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 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 visualization shows population over time by region, with multiple lines representing different areas across a time series from 1950 to 2100. The chart displays data from UN population estimates and medium variant projections, processed through a melting technique that converts wide-format data into long format using `d3.csv`, `d3.timeParse`, and `d3.range`. The visualization uses `d3.scaleTime` and `d3.scaleLinear` for axes, `d3.nest` to group data by region, and `d3.line` with `curveBasis` for smooth paths. A color legend is implemented via a custom `colorLegend` component using `d3.scaleOrdinal` with `schemeCategory10`.

Melting Data for Multiple Lines

This visualization displays population over time by region using multiple lines, with a legend positioned to the right. The chart uses d3.scaleTime, d3.scaleLinear, and d3.scaleOrdinal with schemeCategory10 for color encoding. Data is processed through a custom melt function that reshapes UN population estimates from wide to tidy format, combining estimates from 1950–2014 with medium-variant projections through 2100. The line generator uses curveBasis for smooth paths, while axes employ d3.axisBottom and d3.axisLeft with gridlines.

Melting Data for Multiple Lines

This visualization shows population trends over time for various global regions, with each region represented by a colored line and a corresponding legend. The data comes from UN population estimates and projections, spanning 1950 to 2100. Built with D3 v5, the code melts wide-format CSV data into tidy rows using a custom function before applying scales, axes, and a line generator with curveBasis interpolation. Regions are sorted by their final population value and colored using d3.scaleOrdinal with schemeCategory10.

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.
