Two linked line charts, built with D3 v5, visualize EPA groundwater monitoring data from two observation wells. The main chart displays a trendline calculated with a least-squares regression, while a smaller brush chart allows users to select a date range. The brush selection filters the data and updates the trendline and its equation in the main chart, with a color legend distinguishing the wells.

Fork of Brush, Trendline, Legend, Linechart, Barchart

Two time series of EPA groundwater monitoring data display water levels at a deep and shallow observation well. A linked brush chart below the main line chart filters the date range, and the main chart’s x-axis updates accordingly. A dashed trendline with its regression equation appears in the brushed region, while a legend identifies the two colored lines. The visualization uses d3.scaleTime, d3.line, d3.brushX, d3.nest, and a least-squares regression helper to compute the trendline from filtered data.

Fork of Brush, Trendline, Legend, Linechart, Barchart

The visualization shows groundwater monitoring data from two observation wells at the Bog of the Ring, plotting water levels over time as a line chart with a brushed time-range selector below. A dashed linear regression trendline appears for the selected period, calculated via the least-squares method in the `Regression.js` module. The implementation uses D3 v5 APIs including `d3.brushX`, `d3.scaleTime`, `d3.scaleLinear`, `d3.nest`, and `d3.line`, rendering to SVG with a categorical color scale to distinguish the two wells. Data is loaded from external CSV files.

Brush, Trendline, Legend, Linechart, Barchart

This example visualizes EPA groundwater monitoring data for two observation wells at the Bog of the Ring using D3 v5 with SVG rendering. A main line chart displays water levels over time with an ordinal color scale and legend, while a smaller brush chart below allows users to select a date range. The brushed region updates the main chart’s x-axis domain and fits a least-squares regression trendline with its equation shown. Data is loaded from CSV files, parsed with d3.timeParse, and the chart uses d3.brushX, d3.line, d3.nest, and d3.scaleTime.

Fork of Brush, Trendline, Legend, Title, Linechart, Barchart

This fork of a D3.js example combines a line chart of EPA groundwater monitoring levels with a bar chart of effective rainfall for the Bog of the Ring. A brushed time-series chart filters both views synchronously, and a dashed trendline with its equation updates based on the selected date range. The code uses `d3.brushX`, `d3.scaleTime`, `d3.axisBottom`, and `d3.nest` to build the SVG rendering, with `d3.csv` loading the two datasets. A color legend distinguishes the observation wells and rainfall series.

Fork of Trend line with legend

This example shows two synchronized line charts of water level measurements over time, with a brushable overview chart below that filters the main chart’s visible date range. The main chart displays orange and blue series for two wells, alongside a dashed gray regression trendline computed via least squares and a text label with its equation. A color legend identifies the series. The charts use D3 v5’s `scaleTime`, `scaleLinear`, `line`, `brushX`, and `nest` to render SVG paths, while brushing calls `setBrushCoords` to update the trendline and domain.

Brush, Trendline, Legend, Title, Linechart, Barchart

This visualization shows groundwater monitoring data from EPA wells at the Bog of the Ring, displaying water level measurements as time-series line charts with a brushable overview panel and a bar chart of effective rainfall. Users can brush a date range in the lower chart to filter the main display, which updates the trendline computed via least squares regression and shows the equation. Built with D3 v5, the example uses scaleLinear, scaleTime, brushX, and axis functions for the SVG rendering. The trendline and regression statistics are calculated using a custom leastSquares function.

Brush, Trendline, Legend, Title, Linechart, Barchart

This interactive D3 v5 visualization compares groundwater levels at two EPA monitoring wells against effective rainfall in a swamp marsh, using a main line chart with a linked brush chart and vertical bar histogram. Users brush a time range in the lower chart to filter the main view, which recomputes a dashed trendline via a least-squares regression function and displays its equation. The upper SVG rendering includes dual y-axes, a categorical color legend, and derives data from external CSV files parsed with `d3.timeParse` and plotted with `d3.line`, `d3.brushX`, and `d3.axisBottom`.

Brush, Trendline, Legend, Title, Linechart, Barchart

This example combines a line chart and bar chart to explore groundwater levels at the Bog of the Ring, comparing two observation wells against effective rainfall. A brushed time-series chart filters the main visualization, updating a least-squares regression trendline and its equation. The main chart renders blue and orange lines for well measurements with a bar chart for rainfall, using d3.brushX, d3.nest, and d3.scaleTime. Data loads from CSV files, with SVG rendering and a categorical color legend.
