This example combines d3-brush and d3-zoom to create a Focus + Context interface for exploring time-series data. The main chart (focus) displays the S&P 500 index as a smooth area chart, while a smaller context chart below shows the same data. Users can brush a region in the context chart to zoom the focus view, or scroll/wheel over the focus chart to pan and zoom directly. The two views stay synchronized: brushing the context updates the focus, and zooming in the focus moves the brush. The visualization uses SVG rendering with D3 v4, with axes for time and price, and a clip path to constrain the area mark.

Brush & Zoom

Combining d3-brush and d3-zoom to implement Focus + Context. Another approach is to zoom to the brushed region.

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.

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.

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.

Focus + Context Scatter Plots

This example demonstrates focus+context area charts using D3.js, with a linked brush that filters a detailed view. The main chart (focus) displays the full dataset as a filled area, while a smaller context chart beneath it shows the same data. When a brush is dragged across the context chart, it defines a time interval that automatically updates the focus chart's x-axis domain, enabling zooming and panning. The implementation uses Chiasm components for reactive data flow, with the brush interval acting as a shared state between the two views. The visualization effectively illustrates how brushing and linking can provide both overview and detail in time-series data exploration.

This example combines d3.brush and d3.zoom to implement Focus + Context navigation for a stock price dataset. The main panel displays daily candlestick bars (open, high, low, close) and an area chart of cumulative returns, while a smaller context panel shows the full price range. Dragging the brush in the context panel updates the focus domain, and panning or zooming in the focus area conversely adjusts the brush. The code uses d3.area, d3.axisBottom, and d3.axisLeft, with data loaded from a CSV file.

Area Chart with Brushing

This example presents an area chart of monthly price data from January 2000 through March 2010, rendered as an SVG with a main focus chart and a smaller context panel beneath it. The visualization demonstrates linked brushing: users can select a range on the context panel with a brush, which zooms the focus chart to that time period. The code uses d3’s scaleTime, scaleLinear, area, and brushX APIs, with axes generated by axisBottom and axisLeft. The interactive brushing triggers a zoom by re-computing the x-domain and redrawing the focus area and axis.
