Update graph data automatically

A line chart of stock closing prices automatically refreshes with a new dataset every five seconds. Built with D3.js version 3, the visualization uses `d3.csv` to load two CSV files, `d3.time.scale` for the date axis, and `d3.svg.line` for the path. A `setInterval` triggers the update, which transitions the line and axes over 750 milliseconds using D3’s `.transition()` and `.duration()` methods. The SVG rendering relies on standard D3 SVG elements and selectors to swap the data seamlessly.

AI-generated description

This is a follow on from the update data graph used as an example in the book D3 Tips and Tricks.

It demonstrates the loading of new data for the graph automatically after 5 seconds. It should be taken in context with the text of the book which can be downloaded for free from Leanpub.

Update and revert graph data

Two line charts share a common set of axes, displaying date-based stock closing values. Clicking the "Update" button loads alternate data (`data-alt.csv`) and animates the line and axis ranges over 750 ms using D3 transitions, while "Revert" returns to the original `data.csv` dataset. The visualization uses D3's `d3.time.scale`, `d3.scale.linear`, `d3.svg.line`, and `d3.svg.axis` to render the SVG line and axes, with `.transition()` on the `d3.select("body")` selection to smoothly interpolate the path and axis scales.

Simple line graph in d3.js

This example shows a simple line graph plotting stock closing prices over time, with date values on the x-axis and price on the y-axis. The visualization uses D3.js version 3.5.17, employing `d3.time.scale` for the date range, `d3.scale.linear` for the value axis, and `d3.svg.line` to generate the path. Data is loaded from a local CSV file via `d3.csv`, with the axes created through `d3.svg.axis`. The SVG rendering includes styled axis lines and a steelblue line, providing a minimal teaching example for D3 chart construction.

Untitled

A line chart displays stock closing prices over time for two datasets. An "Update" button triggers an animated transition between the datasets, smoothly interpolating both the line path and the x- and y-axes using D3.js transitions with a 750-millisecond duration. The visualization uses d3.svg.line, d3.time.scale for time-based x-axis formatting, and d3.svg.axis, with data loaded from CSV files via d3.csv. The SVG path and axes are updated in place, demonstrating dynamic data swapping.

Simple d3.js Graph

This simple d3.js graph displays a time series of closing stock prices from a CSV file, with dates on the x-axis and values on the y-axis. Rendered as an SVG line chart, it uses d3.svg.line, d3.time.scale, and d3.scale.linear to map the data, while d3.svg.axis generates the axes. The data.csv file contains 26 daily entries from March to May 2012, positioned within a 600×270 pixel canvas with margins. The code also applies a steelblue stroke to the line and grey axis lines via CSS.

Simple d3.js graph with internal data

This example shows a line chart of stock closing prices over a three-week period in April and May 2012. The data is declared internally as a JavaScript array of date-value pairs. The visualization uses D3.js version 3.5.17, with `d3.time.scale`, `d3.scale.linear`, `d3.svg.axis`, and `d3.svg.line` to render the axes and the line path in SVG. The chart includes styled axes and a steelblue line, with the date parsed via `d3.time.format`.

Update d3.js data with button press

This example demonstrates how to update a line graph by pressing an "Update" button. It uses D3.js version 3.5.17 to render an SVG line chart of date and closing value pairs. The interaction is handled by an HTML `onclick` event that triggers the `updateData()` function, which re-fetches a different CSV file (`data-alt.csv`). The axes and line path are then updated with a smooth 750-millisecond transition, showing how to dynamically replace the dataset and rescale the visualization.

Graph and table with tricks

A line chart of stock closing prices over time is displayed alongside an HTML table listing each date’s close, open, and computed difference. The SVG chart uses d3.time.scale and d3.svg.line to render the path, while d3.csv loads the data. The table is built with d3.select and append, then sorted by closing price in descending order, with column headers capitalized.

Simple Line Graph v7

This chart displays the closing price of a stock over time from late March to early May 2012, using a single blue line. It renders data from a CSV file as an SVG path, with the x-axis showing dates and the y-axis showing price values. The code loads the data via `d3.csv`, parses dates with `d3.timeParse`, scales the axes with `d3.scaleTime` and `d3.scaleLinear`, and draws the line using `d3.line`. It appends axes with `d3.axisBottom` and `d3.axisLeft` to complete the visualization.
