Animated bar chart of historical and projected world population from 1950 to 2100, based on UN estimates. The chart displays bars for multiple regions, with a horizontal line marking the selected region’s population; hovering over a bar highlights it, dims others, and reveals percentage differences relative to the selected region. Built with D3 v5 using `d3.scaleBand`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.select` for SVG rendering. Data is melted from two CSV files via a custom `melt` function, loading UN population estimates and medium variant projections.

Melting data with multiple lines

This chart shows population trends for world regions from 1950 to 2100, using a multi-line plot where each line represents a region’s population over time. It uses D3 v5’s `scaleTime`, `scaleLinear`, `scaleOrdinal` with `schemeCategory10`, `line` with `curveBasis`, and `nest` to group data. The SVG is rendered with axes from `axisBottom` and `axisLeft`, and a custom `colorLegend`. Data comes from UN estimates and medium projections, melted into a tidy format.

Melting Data for Multiple Lines

This chart displays population estimates and projections from 1950 to 2100 for regions worldwide, using multiple lines colored by country and sorted by their final population values. The visualization relies on d3.csv to load UN data, d3.nest to group rows by region, and d3.line with curveBasis to generate smooth paths. A custom colorLegend module renders the categorical color scale, while axes are built with d3.axisLeft and d3.axisBottom, and the data is reshaped through a custom “melting” process that converts wide-format year columns into long-format rows.

Melting Data for multiple lines - new un Data

This visualization displays world population estimates from 1950 to 2100 as multiple smoothed lines, one per region, colored by category. The chart uses d3.line with curveBasis, d3.scaleTime, d3.scaleLinear, and d3.nest to group data, while a custom colorLegend function renders the ordinal color scale with SVG circles and text. Data comes from UN population estimates CSV files, melted from wide to long format.

Melting Data for Multiple Lines

This chart shows projected population growth by region from 1950 to 2100, with each line representing a different world region and colored via a categorical scale. The data is sourced from UN population estimates, loaded from two CSV files and melted into a tidy format. The visualization uses d3.line with curveBasis to smooth the paths, d3.nest to group data by region, and d3.scaleTime and d3.scaleLinear for axes. A custom colorLegend component renders circles and labels in SVG, while axis gridlines and a title complete the layout.

Melting Data for Multiple Lines

This visualization displays projected population changes for countries from 1950 to 2100, using multiple lines to track each nation over time. It employs d3.line with curveBasis smoothing and d3.nest to group data by country, with color-encoded lines and a d3.scaleOrdinal legend. The chart includes a circle marker and label at each line’s final point, with axes from d3.axisLeft and d3.axisBottom. Data comes from UN population estimates CSV files, processed through a custom melt function that transforms wide-format data into tidy rows.

Melting Data for Multiple Lines

This example visualizes population over time by region, showing six major world regions as distinct colored lines from 1950 to 2100. The chart uses a line generator with curveBasis for smooth paths, while a color legend identifies each region. The code melts wide-format UN population data into tidy rows, combining estimates and medium-variant projections from CSV files. It employs d3.scaleTime, d3.scaleLinear, d3.scaleOrdinal, d3.nest, and d3.axisBottom/axisLeft, rendering as SVG with custom tick formatting for abbreviated population values.

Melting Data for Multiple Lines

This example visualizes global population trends from 1950 to 2100, showing how different regions change over time as multiple lines. The chart uses `d3.line` with `curveBasis` to draw smooth paths, with color encoding via `d3.scaleOrdinal` and a custom `colorLegend`. Data is melted from wide to long format using a custom `melt` function that processes UN population estimates from two CSV files, concatenating historical estimates with medium-variant projections. The visualization includes axis labels, gridlines, and a legend, with regions sorted by their final population value.

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.
