candleBars

A candlestick chart visualizes stock price movements over time, showing daily open, high, low, and close values using red and green bars. The visualization uses D3 v4 with SVG rendering, employing `d3.scaleTime` for the x-axis and `d3.scaleLinear` for price values. Each candle consists of a thin line for the high-low range and a rectangle for the open-close spread, colored green for down days and red for up days. Data comes from a CSV file containing date, price, volume, and return columns.

sync candlebar and line, 2-y-axis

This example syncs a candlestick chart of stock price data with a line chart of returns, using two separate y-axes. The left axis shows price (Open, High, Low, Close) via red and green candles for up and down days, while the right axis displays a steelblue line for the return ratio. Built with D3 v4, it uses `d3.scaleTime`, `d3.scaleLinear`, `d3.line` with `d3.curveBasis`, and `d3.axisRight`/`d3.axisLeft`, rendering as SVG from a CSV file. The legend and axis labels clarify the dual metrics.

Candlestick

This example displays a candlestick chart, a financial visualization showing the open, high, low, and close prices for a series of dates. The code renders five candlesticks as SVG rectangles for the price range between open and close, with vertical lines for the high and low extremes. The chart uses d3.scaleTime and d3.scaleLinear to map dates and prices to the 600 by 400 pixel canvas, and d3.axisBottom and d3.axisLeft to draw the axes. Each candlestick is colored green or red via CSS classes based on whether the closing price is higher or lower than the opening price.

30. stock return chart

A single red line charts the daily "return" of a stock, indexed to a base value of 1.0, over several months in 2011. The chart maps dates on the x-axis and the return value on the y-axis, using a basis curve for smoothness. It loads and parses the data from a CSV file with `d3.csv`, formats dates with `d3.timeParse`, and uses `d3.scaleTime` and `d3.scaleLinear` for the axes. The line is rendered as an SVG path via `d3.line`, with axis elements created using `d3.axisBottom` and `d3.axisLeft`.

stock

A multi-line chart animates banking stock prices over time, with each series plotted in its own horizontal band and labeled by symbol. The visualization first draws lines progressively using a `d3.timer`, then transitions into horizon charts by stacking filled areas with a `clipPath`. Data is loaded via `d3.csv` from a gist and parsed with `d3.time.format`. The SVG rendering uses `d3.svg.line`, `d3.svg.area`, and `d3.scale.linear` to map dates and prices, with color assigned by `d3.scale.category10`.

HTML Starter

This example displays a multi-series line chart of stock data, plotting both opening and closing values over time as two distinct colored lines. The visualization uses D3 v4 with SVG rendering, employing `d3.line()` to generate the paths, `d3.scaleTime()` for the time-based x-axis, and `d3.scaleLinear()` for the y-axis. Data is loaded from a local CSV file via `d3.csv()`, with dates parsed using `d3.timeParse()`. The chart includes axes rendered through `d3.axisBottom()` and `d3.axisLeft()`, all styled with basic CSS classes.

Let's make a face with D3.js!

This example shows a dual-line chart comparing stock close and open prices over time, with two colored axes (steel blue for close, red for open) to distinguish the scales. It uses D3 v5’s `d3.csv` to load the data, `d3.timeParse` to format dates, and `d3.scaleTime`/`d3.scaleLinear` for the x and y ranges. The lines are drawn with `d3.line` and appended as SVG paths, with axes rendered via `d3.axisBottom`, `d3.axisLeft`, and `d3.axisRight`. Data comes from `data4.csv`.

Line Chart 4.0

This line chart visualizes daily closing stock prices from April 2007 to June 2008, with time on the x-axis and price in dollars on the y-axis. The SVG rendering uses D3 v4 APIs including `d3.timeParse`, `d3.scaleTime`, `d3.scaleLinear`, and `d3.line` to generate the path, while axes are drawn with `d3.axisBottom` and `d3.axisLeft`. The data is loaded from a tab-separated `data.tsv` file containing date and close columns, with the line styled in steelblue.
