This example visualizes population over time by region from 1950 to 2100, using data from the UN Population Estimates. It displays multiple line paths, each colored by region, with an ordinal color scale and a custom legend. The visualization uses d3.csv, d3.nest, d3.scaleTime, d3.scaleLinear, d3.line with curveBasis, and d3.axisBottom/axisLeft. Data is melted from wide to long format, filtered for regions, and rendered as SVG paths with mix-blend-mode multiplication.

Fork of Melting Data for Multiple Lines

This visualization shows population over time by region, with multiple lines tracking changes from 1950 to 2100. A color legend identifies each region, and the chart displays population values on a logarithmic scale with a title and axis labels. The code uses d3.csv to load UN population estimates and medium variant data, d3.nest to group by region, and d3.line with curveBasis for smooth paths. The colorLegend export creates a custom legend, while d3.axisLeft and d3.axisBottom render the axes.

Fork of Melting Data for Multiple Lines

This chart displays population over time by region, with multiple colored lines showing changes from 1950 to 2100. A legend on the right identifies each region. The visualization uses d3.line with curveBasis for smooth paths, d3.scaleTime and d3.scaleLinear for axes, and d3.nest to group data by region. Data comes from UN population estimates and medium variant projections, processed through a custom melt function. The color legend is rendered using a custom colorLegend module.

Fork of Melting Data for Multiple Lines

This visualization shows population over time by region, with multiple lines depicting trends from 1950 to 2100. The code uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `line`, `curveBasis`, `nest`, and `axisLeft`/`axisBottom` to render SVG paths with a color legend. Data comes from UN population estimates and medium variant projections, processed by melting wide-format CSV data into tidy long-form rows.

Fork of Melting Data for Multiple Lines

This example visualizes population over time by region from a UN dataset, showing multiple lines from 1950 to 2100 using nested data. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, and `scaleOrdinal` for axes and color, with `axisBottom` and `axisLeft` for tick marks. Lines are generated via `line` with `curveBasis`, and a custom `colorLegend` function displays the categorical color scale. The code employs `nest` and `descending` to sort regions by their final population value, rendering the SVG with a multiply blend mode.

Fork of Melting Data for Multiple Lines 12

This visualization shows regional population trends over time, with multiple colored lines representing different world regions from 1950 to 2100. The chart uses a line chart with a time-based x-axis and a population y-axis, featuring interactive zoom functionality. The code leverages d3.csv, d3.nest, d3.line with curveBasis, d3.scaleTime, and d3.scaleOrdinal with schemeCategory10. A custom colorLegend component renders a categorical legend. The data comes from UN population estimates, processed through a custom melt function that reshapes the dataset for visualization. The SVG rendering includes grid lines and axis labels.

Fork of Melting Data for Multiple Lines

This visualization shows population trends over time for global regions, with multiple colored lines tracking each region’s population from 1950 to 2100. Data comes from UN population estimates merged with medium-variant projections. Using D3 v5, the code employs `d3.csv`, `d3.nest` for grouping, `d3.scaleTime`, `d3.scaleLinear`, and a custom color legend to distinguish regions. Lines are drawn with `d3.line` and `curveBasis`, while axes and labels use `d3.axisLeft` and `d3.axisBottom`, rendered as SVG.

Fork of Melting Data for Multiple Lines

This chart displays population over time by region, using multiple smoothed lines to compare trends from 1950 to 2100. The code uses d3.csv to load UN population estimates and a medium variant projection, then d3.nest to group data by region and d3.line with curveBasis to generate the paths. Axes are rendered with axisBottom and axisLeft, while a custom colorLegend function handles the categorical color scale. The visualization is drawn as an SVG with a title and axis labels.

Fork of Melting Data for Multiple Lines

This visualization shows population trends over time for global regions, with multiple colored lines plotted on axes labeled “Time” and “Population.” The data combines UN population estimates from 1950–2014 with medium-variant projections from 2015–2100, processed through a custom `melt` function. It uses d3.scaleTime, d3.scaleLinear, d3.scaleOrdinal with schemeCategory10, d3.line with curveBasis, d3.nest for grouping, and axis generators with tick formatting. A custom colorLegend component displays the categorical color scale, while SVG paths are styled with mix-blend-mode for overlapping lines.
