Forked from Multing Data for Multiple Lines

This visualization shows population trends over time for multiple world regions, with each line color-coded and sorted by its final population value. The chart includes axes with gridlines, a legend generated by a custom `colorLegend` function, and smoothed lines using `curveBasis`. Data is processed by melting wide-format CSV rows from UN population estimates into tidy long-form data, then nested by region with `d3.nest`. The visualization uses `d3.scaleTime`, `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.line`, rendering to SVG with D3 v5.

Multing Data for Multiple Lines

This visualization displays population trends over time for various regions, with each line representing a different area and color-coded via a categorical scale. It uses d3.line with curveBasis to generate smooth paths, d3.nest to group data by region, and d3.scaleOrdinal for colors. Population estimates from UN data are melted into a tidy format, with axes formatted using d3.axisBottom and d3.axisLeft. A custom colorLegend component renders the legend alongside the SVG chart.

Multing Data for Multiple Lines

This chart displays population estimates and projections over time for various world regions. A legend uses color to distinguish the regional lines. The data is loaded from two CSV files and processed with the `melt` function. The visualization is rendered as an SVG using D3 v5, employing `scaleTime`, `scaleLinear`, and `axisBottom` for axes, and `line` with `curveBasis` for the curves. The lines are colored using `schemeCategory10` and the chart includes a custom color legend.

Melting Data for Multiple Lines

This visualization displays population trends over time for various world regions using multiple lines. The chart combines historical estimates from a 2017 UN dataset with medium-variant projections through 2100, showing each region’s population trajectory in a distinct color. The code uses d3.csv to load data, d3.nest to group by region, d3.line with curveBasis for smooth paths, and d3.scaleTime and d3.scaleLinear for axes. A custom colorLegend component renders the categorical scale, while d3.axisLeft and d3.axisBottom create labeled tick marks.

Melting Data for Multiple Lines

This visualization displays the history and future of world population as multiple lines, one per country or region, sorted by their final population value. The chart uses a time-based x-axis and a linear y-axis with formatted tick labels, while a color-coded legend identifies each line. Built with D3 v6, the example uses `d3.nest()` to group melted data from two UN population CSV datasets, `d3.line()` with `curveBasis` to generate smoothed paths, and a custom `colorLegend` component to render the ordinal color scale legend.

D3 Melting Data for Multiple Lines

This visualization displays population trends over time for various world regions, with multiple colored lines representing different areas. The chart uses D3's `scaleTime` and `scaleLinear` to map the data for the x and y axes, and `scaleOrdinal` with `schemeCategory10` for line colors. The code uses D3's `nest` function to group the data by region name, and employs `line` with `curveBasis` for smooth curve rendering. The data is melted from UN population estimates and medium variant projections, covering years from 1950 to 2100. A custom `colorLegend` component renders the color guide for the regions.

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.

Melting Data for Multiple Lines

This visualization shows population trends over time for global regions, displaying multiple lines on a chart with a color-coded legend. The data is sourced from UN population estimates and projections, spanning from 1950 to 2100. The code uses d3.csv and d3.nest to process and group the data, while d3.line with curveBasis generates the smooth paths. Color is assigned via d3.scaleOrdinal with schemeCategory10, and the chart includes axes rendered with d3.axisBottom and d3.axisLeft, with a custom color legend component for identifying each region.

Melting data for multiple lines

This visualization shows population trends over time for global regions, with each region drawn as a separate colored line and a legend identifying the regions. The data comes from UN population estimates (1950–2014) and medium-variant projections (2015–2100), melted into tidy format. The code uses d3.csv, d3.nest, d3.scaleTime, d3.scaleLinear, d3.scaleOrdinal, d3.line with curveBasis, and d3.axisLeft/axisBottom. A custom colorLegend module renders the legend, while SVG paths with mix-blend-mode multiply display overlapping lines.
