This line chart visualizes world population over time by region, with each region drawn as a distinct colored line on an SVG canvas. The chart uses D3 v5 APIs including `d3.scaleTime`, `d3.scaleLinear`, `d3.line` with curveBasis, and `d3.nest` to group data. Population estimates from 1950–2014 and medium-variant projections from 2015–2100 come from UN datasets loaded via `d3.csv`. A color legend using `d3.scaleOrdinal` maps regions, and a vertical line marks the year 2021, with mouse interaction logging hovered years to the console.

Line Chart with Multiple Lines

This line chart visualizes global population trends over time, grouped by world regions, using a multi-line layout with a categorical color legend. It combines historical estimates (1950–2014) with medium-variant projections (2015–2100) from UN population data. The visualization uses D3 v5 with `scaleTime`, `scaleLinear`, `scaleOrdinal`, `axisLeft`, `axisBottom`, `line`, `curveBasis`, and `nest` to structure and render the paths, while a custom `colorLegend` function displays the region labels as SVG circles and text.

Line Chart with Multiple Lines

This visualization shows population trends over time for multiple world regions, with each region represented as a distinct colored line and a legend identifying the regions. A vertical black line marks the currently selected year, and users can move their mouse across the chart to dynamically change that year. The code uses d3.line, d3.scaleTime, d3.scaleLinear, and d3.scaleOrdinal to render SVG paths, along with d3.nest to group the data by region. Population data comes from UN estimates and medium-variant projections, covering 1950 to 2100.

Line Chart with Multiple Lines

This line chart displays projected population trends over time for multiple world regions, with each region represented by a colored line and a corresponding color legend. The chart uses d3.line with curveBasis to create smooth paths, d3.nest to group data by region, and d3.scaleOrdinal with schemeCategory10 for coloring. Axis labels and gridlines are generated using d3.axisBottom and d3.axisLeft. The data comes from UN population estimates and medium-variant projections, which are processed and merged using d3.csv, d3.range, and d3.timeParse.

Line chart with multiple lines

This line chart displays population trends over time for global regions, with each region represented by a colored line and a legend identifying them. The data spans from 1950 to 2100, combining UN population estimates and medium-variant projections processed through a custom melt function. The visualization uses d3.scaleTime, d3.scaleLinear, and d3.scaleOrdinal with schemeCategory10, while d3.line with curveBasis generates the smoothed paths. Axis labels, grid lines, and a title are rendered via d3.axisBottom, d3.axisLeft, and SVG text elements.

Line Chart

This example shows world population trends as a line chart, plotting year on the x-axis against percentage on the y-axis. The chart uses D3 v5 with an SVG rendering approach, employing `scaleTime` and `scaleLinear` for the axes and `line` to generate the path. Data is loaded from a CSV file via `csv`, with axes labeled and styled using `axisBottom`, `axisLeft`, and CSS. The line is drawn with a pink stroke, and the chart includes a title and axis labels.

linechart

This line chart visualizes world population trends from 2010 to 2020, with time on the x-axis and population count on the y-axis. The chart is rendered as an SVG using D3 v5, with the line path styled in violet and grid lines in green. The code imports components like `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` to construct axes, and parses CSV data from a GitHub gist. Data values are formatted and axis labels are customized through D3’s `axis` and `text` APIs.

Selecting a Year on a Line Chart

This line chart displays global population trends for regions from 1950 to 2100, with a movable vertical line that lets the user select a specific year. The chart highlights population values for that chosen year via circles on each regional line, with a color legend identifying each region. Built with D3 v5, the visualization uses `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` to render the SVG chart. Data comes from UN population estimates and medium variant projections, loaded via `csv` and processed through `nest` and `melt` functions. Hover interactions are handled by the `mouse` callback on an invisible rectangle.

Selecting a Year on a Line Chart

This visualization displays population trends over time for various world regions using a line chart, rendered with SVG. Users can hover over the chart to select a specific year, which updates a vertical black line to mark that point in time. Built with D3 v5, the code utilizes `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` for axes, `line` with `curveBasis` for the paths, and `nest` to group data by region. The color legend is created using `scaleOrdinal` with `schemeCategory10`. Data comes from UN population estimates.
