Yahoo Finance Chart Step 5 - Volume Chart

Yahoo Finance Chart Step 6 - Volume Chart Decorated

This example presents an intraday Yahoo Finance chart that combines a decorated price series with a volume chart. The price panel shows the open price as a gradient-filled area, a blue line, and a red exponential moving average (EMA), all overlaid with gridlines using the d3fc library. The lower volume panel renders bars colored red or green based on whether the close price is above or below the open. The chart uses d3.csv to load the data, d3.time.format for axis labels, and d3.svg to render the SVG output.

Yahoo Finance Chart Step 4 - Moving Average

This example shows a Yahoo Finance intraday chart for a stock, combining an area series of opening prices with a blue line and a red exponential moving average line, plus gridlines. The chart uses the d3fc library’s `fc.chart.linearTimeSeries`, `fc.series.area`, `fc.series.line`, and `fc.indicator.algorithm.exponentialMovingAverage` components, all rendered as SVG. Data is loaded from a CSV file via `d3.csv` and parsed into date objects. The moving average is computed over a window size of 20 on closing prices, with axes configured to display time and price.

Yahoo Finance Chart Step 9 - Legend

This example shows a Yahoo Finance time-series chart of stock price data, displaying open, high, low, close, and volume values with a moving average line, price callouts, and a legend. It uses the d3fc library's `fc.chart.linearTimeSeries` and `fc.chart.legend` APIs, along with D3.js for rendering SVG. The chart combines area, line, and bar series, and colors volume bars red or green based on price movement. Data is loaded from `yahoo.csv` and parsed from timestamps into dates.

Yahoo Finance Chart Step 1 - Basic Chart

This example shows a basic time-series area chart of Yahoo Finance stock prices, plotting opening values over time as a filled area. The visualization uses the d3fc library’s `fc.chart.linearTimeSeries` and `fc.series.area` components, with D3’s `d3.csv` loader parsing timestamps into JavaScript Date objects. The chart is rendered as an SVG element, with data read from a local CSV file containing timestamp, open, high, low, and close price columns. The x- and y-domains are automatically calculated from the data using `fc.util.extent`.

Yahoo Finance Chart Step 7 - Annotations

This example shows an intraday stock chart for Yahoo Finance data, combining price and volume. It plots a line and area chart for open prices, overlays an exponential moving average, and draws current-value annotation lines for both the close and the moving average. Volume is displayed as colored bars, using red or green strokes depending on whether the close is above or below the open. The visualization is built with D3 and the d3fc library, using SVG rendering and a CSV data source.

Yahoo Finance Chart Step 8 - Callouts

This example demonstrates a Yahoo Finance chart of stock prices, using an area and line series to show the opening price over time, with a red moving average line overlaid. The chart uses D3.js with the d3fc library, rendering to SVG. It highlights the final values of the close price and the exponential moving average using styled callout annotations with labels. The data is loaded from a CSV file, and volume bars appear below the main time series, colored red or green based on price movement.

Yahoo Finance Chart Step 2 - Gidlines and Area

This example shows a financial time series chart of Yahoo stock prices, plotting open values as both a filled area and an overlaid line against timestamps. The chart uses horizontal gridlines for scale reference, with five y-axis ticks and a cleaned domain for readability. Built with D3 and the d3fc library, the code constructs a `linearTimeSeries` chart, composes area, line, and gridline series via `fc.series.multi`, and renders the result as an SVG. Data is loaded from a CSV file.

Yahoo Finance Chart Step 13 - Vertical Bands

This visualization shows a Yahoo Finance candlestick chart with a high-low range area, a 20-period exponential moving average, and volume data, with trading hours handled via a custom discontinuity scale. The chart uses d3fc components for the time-series layout, annotation lines, and legend, while the crosshair feature displays tooltip callouts for price and time values. Data comes from a Yahoo Finance JSON feed and is filtered to regular trading hours, with the full SVG rendered using D3.js.
