Forked from Selecting a Year on a Line Chart

This interactive line chart displays population over time for different world regions, with a vertical line marking the currently selected year. Users can hover anywhere on the chart to update the selection and the line position. Built with D3 v5, it uses `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis`, plus `nest` for grouping data by region. The visualization renders as SVG and loads UN population estimates from CSV files, using `mouse` events to trigger selection updates.

Selecting a Year on a Line Chart

A line chart shows population over time for world regions, with a movable vertical line for selecting a specific year. Users drag the mouse across the chart, which updates the selected year and redraws the line. The visualization uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `line`, `curveBasis`, `nest`, `axisLeft`, `axisBottom`, and `mouse`. Data comes from two CSV files (UN population estimates and medium variant) parsed with `timeParse`, and the chart renders as SVG with a color legend using `scaleOrdinal`.

Selecting a Year on a Line Chart

This line chart shows population over time for different world regions, with a vertical line marking a selected year. Users can hover over the chart to change the selected year, which adjusts the line's position. The visualization uses D3.js v5 to render SVG elements, including a color legend, axes, and multiple line paths. It also employs D3's scale functions, line generator, and mouse event handling to update the chart dynamically based on the United Nations population dataset.

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.

Selecting a Year on a line chart

This interactive line chart displays population changes over time for multiple world regions, using a vertical black line to mark a user-selected year. Moving the mouse across the chart updates the selected year, which is reflected in the line’s position. The visualization is built with D3 v5, using `d3.line` for the paths, `d3.axisBottom` and `d3.axisLeft` for axes, and a `mousemove` event listener on a transparent overlay rect to trigger year changes. Data comes from UN population estimates and medium variant projections, rendered as SVG.

Selecting a Year on a Line Chart

This interactive line chart visualizes population trends over time by region, with a focus on a selected year. The visualization displays multiple region lines and a movable vertical line; as the user moves the mouse across the chart, the selected year is updated and crosshairs track the cursor. Data is sourced from UN population estimates, and the chart is built with D3 v5, specifically using `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `curveBasis`. The rendering uses SVG and includes a color legend. Interaction is handled via an overlay rectangle’s `mousemove` event, which inverts the D3 scales to update the selection.

Selecting a Year on a Line Chart

This visualization displays population trends over time for global regions, with a vertical line marking the currently selected year. Users can hover over the chart to change the selection, which updates the highlighted year. The chart uses D3 v5 with SVG rendering, employing scales like `scaleTime` and `scaleLinear` for axes, and `d3.line` with `curveBasis` for smooth paths. Data comes from UN population estimates and medium variant projections, processed via `d3.csv` and `d3.nest`. A custom color legend shows region names, and the selection uses mouse events to update the year.

Selecting a Year on a Line Chart

This interactive line chart visualizes population trends over time for global regions, with a mouse-driven vertical line denoting the currently selected year. Moving the cursor across the chart dynamically updates the blue selection line, highlighting population values at that moment. The visualization uses D3 v5 with SVG rendering, employing `d3.nest` to group data, `d3.scaleTime` and `d3.scaleLinear` for axes, and a custom `colorLegend` module for categorical color encoding. Data comes from UN population estimates and medium-variant projections, spanning 1950 to 2100.

Selecting a Year on a Line Chart

This line chart displays population trends over time for global regions, with a draggable vertical line enabling year selection. The chart updates dynamically as users hover, highlighting the selected year across all series. Built with D3 v5, it uses `nest()` for data grouping, `scaleTime` and `scaleLinear` for axes, and `line()` with `curveBasis` for smooth paths. Data comes from UN population estimates (1950-2100), with a color legend and axis labels rendered as SVG elements.
