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.

AI-generated description

This is a follow on from the simple scatterplot used as an example in the book D3 Tips and Tricks.

It is aimed at demonstrating a the use of an if statement to select elements in d3.js. It should be taken in context with the text of the book which can be downloaded for free from Leanpub.

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 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 v4

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.

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.

Filtering in d3.js

This example shows a time-series line chart of stock closing prices, with a scatterplot overlay. A filter selects only data points with a closing value below 400, rendering those specific circles in red. The chart is rendered as an SVG using d3.js, employing the d3.time.scale and d3.scale.linear for axes, and the .filter() method on the circle’s enter selection to conditionally style points. The data comes from a CSV file with date and close columns.

Filtering in d3.js

This example demonstrates how the `.filter` method in d3.js selectively highlights data points on a line chart. It plots a time series of stock closing prices from a CSV file, drawing a smooth line for the full dataset, then overlays red circular dots only for values below 400. The visualization uses d3.svg.line for the path, d3.time.scale for the date axis, and d3.svg.axis for tick marks. The filtering occurs on circle elements appended via the data join, applying the condition directly to the data array before setting visual attributes.

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.

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.
