This example visualizes stock closing prices over time using a combined line and scatterplot. The code plots each date’s close value as a small circle, with a steelblue line connecting the points to emphasize the overall trend. It uses d3.v3 with SVG rendering, employing d3.time.scale for the date axis and d3.scale.linear for the price values. The axes are generated via d3.svg.axis, while the line is drawn with d3.svg.line and the points are appended as SVG circle elements. Data comes from a local CSV file containing date and close columns.

Simple scatterplot with d3.js

This example shows a hybrid line-and-scatterplot of stock closing prices over time, with a steelblue line connecting daily data points and small circles marking each individual value. The code loads date and close values from a CSV file using d3.csv, parses dates with d3.time.format, and scales the data with d3.time.scale and d3.scale.linear. It renders axes with d3.svg.axis and draws the line using d3.svg.line, while circles are appended to the SVG canvas with explicit cx and cy attributes.

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.

Simple scatterplot with d3.js

This visualization combines a line graph and scatterplot to show Apple’s stock closing price over time, with data from a CSV file. The blue line connects daily price points, while small circles mark each individual observation along the series. Built with D3.js (version 3.5), it uses `d3.svg.line`, `d3.time.scale`, and `d3.svg.axis` to render the SVG path, axes, and date-based x-scale. The scatterplot circles are appended via `selectAll("dot")` with explicit radius and coordinate attributes. Data parsing relies on `d3.time.format` for date conversion and linear scaling for y-values.

Simple line graph in d3.js

This simple line graph plots stock closing prices over time from a CSV dataset with date and value columns. The visualization uses d3.v3 with an SVG canvas, a time-scaled x-axis, and a linear y-axis, rendering the data as a single steelblue path. The code demonstrates core D3 concepts including `d3.time.format` for date parsing, `d3.time.scale` and `d3.scale.linear` for coordinate ranges, and `d3.svg.line` to generate the line geometry from the parsed data points.

Simple scatter plot in v4

This example shows a simple line graph with circular data points overlaid to create a scatter plot, displaying stock closing prices over time. The visualization uses d3.csv to load the data, d3.timeParse to convert date strings, and d3.scaleTime and d3.scaleLinear to map the date and price values to pixel coordinates. A d3.line generator draws the line path, while appended circle elements mark each data point. The chart includes axes generated with d3.axisBottom and d3.axisLeft, all rendered as SVG within the page.

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.

Scatterplot with v5

This example shows a time-series line graph of stock closing prices, with circular scatterplot points overlaid on each data value. The visualization uses a steelblue line and dark circles to highlight individual daily observations across the date range. Built with d3 v5 and rendered as SVG, the code employs `d3.csv` to load the data, `d3.timeParse` for date formatting, and `d3.line` for the path, while `d3.scaleTime` and `d3.scaleLinear` handle the axes. The scatterplot points are appended as SVG circles positioned via the same x and y scales.

20 - Simple graph and table using d3.js

This example displays a time-series line chart of stock closing prices alongside a table of the same data. The SVG line graph uses d3.svg.line to plot dates against close values, with d3.time.scale and d3.scale.linear handling the axes. Below the chart, a table is generated with d3.select and data joins, rendering the raw CSV rows in a Courier font. The visualization reads from data.csv and uses d3.v3, with parsing via d3.time.format.
