This example shows the monthly price of the S&P 500 index from 2000 to 2010 as elongated, semi-transparent "pill" markers in a focus-plus-context scatter plot. Users can brush a time range in the lower context panel, which triggers a callback to zoom the upper focus panel into that selection. Built with d3.v4, the code uses `d3.scaleTime`, `d3.scaleLinear`, `d3.brushX`, and `d3.axisBottom` to render both axes and the brush interaction. Data is loaded from a local `sp500.csv` file and drawn as SVG rectangles in the focus view and circles in the context view.

Brush & Zoom

This example shows a focus and context view of the Standard & Poor’s 500 stock index over time, with a large area chart on the top and a smaller overview below. A colored brush in the context pane selects a date range, while a transparent rectangular overlay on the focus pane enables direct zooming and panning via the `d3.zoom` API; both interactions synchronize the visible data domain. The code combines `d3.brushX` with `d3.zoom`, and uses `d3.scaleTime`, `d3.axisBottom`, and `d3.area` to render the monthly price data from the CSV file as scalable vector graphics (SVG).

Brush & Zoom

This example implements a focus-plus-context visualization of monthly S&P 500 closing prices. The large focus chart displays the full time series as an area chart, while a smaller context chart below it includes a draggable brush for selecting a date range; zooming is performed via a transparent overlay rectangle supporting wheel and drag interactions. It uses the d3.brushX component for the selection and d3.zoom for the pan-and-scale transform, with both updating the focus area's x-axis domain. The data is loaded from a CSV file (sp500.csv), and all graphics are rendered as SVG paths.

An interactive area chart displays monthly S&P 500 price data. The visualization uses a focus-and-context technique, combining a large main chart with a smaller overview panel. Users can brush a region in the context panel to zoom the focus area, or directly pan and zoom the focus chart itself. The example uses d3.brush and d3.zoom, with d3.area for the line, and d3.axisBottom and d3.axisLeft for the axes, rendering as SVG.

Brush & Zoom

This example demonstrates a Focus + Context visualization of S&P 500 monthly prices, combining brushing and zooming. The main chart displays the full time series, while a smaller context chart below shows the entire dataset with a brushable selection window. Users can either drag a brush on the context chart to define a focused region, or scroll/pinch on the main chart to zoom. The two interactions are synchronized via d3-brush and d3-zoom, with the y-scale automatically rescaling to the visible date range. The area chart uses a monotone-x curve, with the focus area clipped and styled in steel blue.

Untitled

This example demonstrates a linked dataset of monthly S&P 500 index prices from a CSV file, presented as a brushable area chart. Users can adjust the visible time range by dragging a brush in the lower context panel, which updates the main focus chart’s x-axis domain. The code uses `d3.brushX` for selection, `d3.zoom` for panning, and `d3.area` with `d3.curveMonotoneX` to render the paths. Both charts are drawn in SVG with axes generated by `d3.axisBottom` and `d3.axisLeft`.

Area Chart with Brushing

This area chart displays monthly S&P 500 price data from January 2000 through March 2010, rendered as a brushed time series. The visualization shows price fluctuations over time in steel blue, with an interactive brushX selection tool below the main chart that allows users to zoom into specific date ranges. The example uses d3.v5 with SVG rendering, employing scaleTime, scaleLinear, axisBottom, axisLeft, brushX, and area functions to construct the focus and context views, with data loaded from a CSV file.

Brush & Zoom

This example demonstrates a Focus + Context technique for time-series data, combining brushing and zooming to explore the S&P 500 index. The main chart displays the full time series as an area, while a smaller context chart below shows the same data. Users can brush a region in the context chart to zoom into that time range in the focus chart, or use the mouse wheel to pan and zoom directly on the focus view. The y-axis dynamically rescales to the visible data, and the brush handle in the context view updates accordingly. The implementation uses D3 v4 with SVG, featuring two area charts with synchronized scales, a brush for selection, and a zoom behavior for interactive navigation.

Brush & Zoom

This example combines d3-brush and d3-zoom to implement a Focus + Context visualization of the S&P 500 index. The main chart displays the full time series as a blue area, while a smaller context chart below shows the same data with a brushable selection window. Users can either drag the brush handle in the context view to select a date range, or pan/zoom directly on the focus view. The two views are synchronized bidirectionally, so brushing the context updates the focus, and zooming in the focus updates the brush selection. The code enforces a minimum brush size to prevent over-zooming, and uses d3.zoom's transform to rescale the x-scale during pan/zoom interactions.
