This visualization shows population change over time as a set of semitransparent, overlapping lines, with each line representing a different region and a color legend on the right. The data comes from a CSV file containing UN population estimates and projections, melted into a tidy format before rendering. Built with D3 v5, the code uses `d3.nest()` to group data by region, `d3.line()` with `curveBasis` for smooth paths, and `d3.scaleOrdinal` with `schemeCategory10` for colors. The chart is rendered as SVG with axes, gridlines, and a custom color legend component.

MULTILINE MELTED

This visualization shows population projections by continent from 1950 to 2100, using a multi-line chart where each line represents a region. The lines are smoothed with a basis curve and blended together using a multiply effect. The code leverages d3.csv, d3.nest, d3.scaleTime, d3.scaleLinear, and d3.axisBottom/axisLeft, with data sourced from UN population estimates and medium-variant projections. A categorical color scale with a custom legend orders the regions by their final population values.

Melting Data Multiple Lines

The visualization shows population over time by region as multiple smoothed lines, with a color legend and axis labels. It uses D3 v5 APIs including `nest()` for grouping, `line()` with `curveBasis` for path generation, `scaleTime` and `scaleLinear` for axes, and `scaleOrdinal` with `schemeCategory10` for colors. Data is melted from UN population estimates and medium variant CSV files, spanning 1950 to 2100, rendered as SVG paths with multiply blend modes.

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 displays regional population changes over time as multiple colored lines, with a vertical marker indicating the currently selected year. Users hover over the chart to update the selection, and a legend identifies each region. Built with D3 v5, it uses `nest` to group data by region and `scaleOrdinal` for colors, rendering with SVG. The data is sourced from UN population estimates, melted into tidy format for the line chart.

Melting Data for Multiple Lines

This visualization shows population over time by region, with multiple smoothed lines drawn from 1950 to 2100 using a basis curve. The code melts wide-format UN population data into tidy rows via a custom `melt` function, then uses `d3.nest()` to group by region and `d3.scaleOrdinal` with `schemeCategory10` for colors. A color legend, axis labels, and gridlines are rendered in SVG. Data merges two CSV sources for estimates and medium-variant projections.

MULTILINE MELTED

This chart displays projected population trends for world regions from 1950 to 2100, with each region shown as a distinct colored line. It uses D3.js v5 to load CSV data, melt it into a tidy format, and render an SVG line chart with a time-scaled x-axis and linear y-axis. The color legend is ordered by each line’s final population value, using D3’s `nest` and `descending` functions. The data originates from UN population 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.
