This example shows a line chart of stock closing prices over time, with points colored conditionally based on their value. The visualization combines a steelblue line path with circles that are red when the closing price is 400 or below and black otherwise. It uses d3.csv to load the data, d3.timeParse for date parsing, and d3.scaleTime and d3.scaleLinear for axes. The if statement inside the circle fill function demonstrates how to apply category-based styling within a d3.v4 data join.

AI-generated description

This is a simple graph demonstrating the addition of filtering using an if statement with a graph. This was written using d3.js v4 and is a follow on to the simple scatter plot example here.

This graph is part of the code samples for the update to the book D3 Tips and Tricks to version 4 of d3.js.

Using an 'if' statement in v6

This example combines a line chart and scatterplot to show stock closing prices over time, with circles colored red when the price is 400 or below and black otherwise. It uses d3.line to generate the line path, d3.scaleTime and d3.scaleLinear for the axes, and d3.axisBottom and d3.axisLeft to render them. Data is loaded from a CSV file via d3.csv and parsed with d3.timeParse. The coloring logic relies on an if statement inside the fill function.

Using an 'if' statement in v5

This example shows a time-series line chart of stock closing prices over a month, with an overlaid scatterplot of individual data points. The points are colored conditionally: red when the closing price is less than or equal to 400, and black otherwise. Built with d3.js v5 and rendered as SVG, it uses `d3.line`, `d3.scaleTime`, `d3.scaleLinear`, and `d3.axisBottom`/`d3.axisLeft`. Data is loaded from a CSV file and parsed with `d3.timeParse`. A simple inline `if` statement within the fill function demonstrates filtering logic for visual encoding.

Using an 'if' statement in v7

This example shows a line graph of stock closing prices over time, with data points color-coded based on their value. The visualization uses SVG rendering and the d3.v7 library, specifically `d3.line`, `d3.scaleTime`, `d3.scaleLinear`, and `d3.axisBottom`/`d3.axisLeft`. It reads CSV data from `data.csv` via `d3.csv` and parses dates with `d3.timeParse`. Each data point is drawn as a circle whose fill color is determined by an `if` statement: values at or below 400 appear red, while higher values are black.

if selection in d3.js

This example demonstrates how to use an `if` statement within a D3.js data visualization to conditionally style elements. A scatterplot line graph displays stock closing prices over time from a CSV file, with each data point colored either red or black based on whether its value is below or above 400. The code uses the D3.js library to parse dates, create a time-scaled x-axis, apply a linear y-axis, and render both a line path and circular points via SVG.

Filtering in v4

This example demonstrates filtering in d3.js v4 by showing a line chart of stock closing prices over time, with red dots highlighting only the data points where the closing price falls below 400. The visualization pairs a steelblue line with scatterplot circles, using the `filter` method on the circle selection to exclude points above the threshold. It loads data from a CSV file, parses dates with `d3.timeParse`, and renders both an SVG line and axis through `d3.axisBottom` and `d3.axisLeft`. The code relies on d3.v4’s scale functions (`d3.scaleTime`, `d3.scaleLinear`) and the `d3.line` generator.

Line graph with gradient in v4

This example shows a line graph of stock closing prices over time, with the line colored by a vertical gradient that shifts from red to black to green based on price levels. The visualization uses d3.v4 to load CSV data, parse dates with `d3.timeParse`, and render an SVG path via `d3.line`. A `linearGradient` with multiple stop points is applied to the line’s stroke, and axes are added using `d3.axisBottom` and `d3.axisLeft`. The data is drawn from `data.csv` containing date and close values.

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.

Scatterplot with v4

This example shows a line graph of stock closing prices over time, with scatterplot points overlaid on the line to mark individual data values. The code loads a CSV file with dates and closing prices, parses the dates with `d3.timeParse`, and defines scales using `d3.scaleTime` and `d3.scaleLinear`. It renders the line with a `d3.line` path and adds circles for each data point using SVG. Axes are drawn with `d3.axisBottom` and `d3.axisLeft`. The visualization uses d3.v4 and is rendered as SVG in the browser.
