A line chart displays stock closing prices over time, automatically swapping between two datasets every five seconds using a `setInterval` loop. The visualization uses D3 v3 to load CSV data via `d3.csv`, parse dates with `d3.time.format`, and render SVG paths with `d3.svg.line`. Smooth transitions animate the line and both axes using `transition().duration(750)`, updating the scales (`d3.time.scale`, `d3.scale.linear`) to match the new data range. Grid lines and an area fill under the curve support the primary line chart.

5 - Update d3.js data with button press

A line chart displays stock closing prices over time, with an area fill beneath the line. A button press triggers an update that swaps the plotted dataset from one CSV file to another, re-scaling the x and y axes accordingly. The visualization uses d3.svg.line and d3.svg.axis, with transitions on the line and axis elements via .transition().duration(750). The data comes from two local CSV files, parsed with d3.time.format, and the chart is rendered in SVG.

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.

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.

1 - Simple d3.js Graph

This example plots a line chart of closing stock prices over time, with values read from a local CSV file containing date and close columns. The visualization uses D3.js v3 to create an SVG-based graph, employing `d3.svg.line`, `d3.time.scale`, and `d3.scale.linear` to map dates and prices to screen coordinates. It renders axes via `d3.svg.axis` with a bottom time axis and a left linear axis, while the line itself is drawn as a path with a steelblue stroke. The graph includes no interactive features or additional data layers, focusing solely on the basic line chart display.

Update d3.js data with button press

This example demonstrates how a line chart can be updated with new data when a user presses an Update button. The visualization initially plots date-stamped stock close values from `data.csv` as a steel-blue line, with axes scaled to the data range. Pressing the button triggers the `updateData()` function, which loads `data-alt.csv` and redraws the line and axes with a smooth 750-millisecond transition. Built with d3.v3, the code relies on `d3.csv` for file loading, `d3.time.scale` and `d3.scale.linear` for scaling, and `d3.svg.line`, `d3.svg.axis`, and `transition()` for animated updates.

6 - Update and revert Graph data

Two buttons, Update and Revert, toggle between two CSV datasets that share the same date range but have different closing values. A single line chart animates smoothly as the path and both axes transition to the new data, with the y-axis rescaling to accommodate the changed price range. The example uses d3.svg.line for the path, d3.svg.axis for the axes, and transition() with a 750-millisecond duration to animate the updates. It demonstrates how to reuse the same scales and axes across multiple data loads while preserving a consistent visual context.

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.

Graph and table with tricks in v7

A line chart displays closing stock prices over time, paired with an HTML table of the same data that adds an open-price column and a computed price-difference column. The table rows are sorted by closing price in descending order using `d3.descending`, and headers are capitalized via text manipulation. The visualization uses the D3 v7 library, with `d3.csv` loading the dataset, `d3.timeParse` for dates, `d3.scaleTime` and `d3.scaleLinear` for axes, and SVG paths rendering the line.
