This example visualizes gene mappings by rendering each gene as a colored rectangle positioned along a horizontal axis according to its start and stop coordinates. Genes on the forward orientation appear in purple on an upper track, while reverse-oriented genes appear in teal on a lower track, with labels centered above each rectangle. The visualization uses D3.js v4’s selection and data join methods to bind the JSON data to SVG groups, then appends rectangles and text elements with attributes computed from the data. The code directly maps each gene’s orientation to its vertical placement and fill color.

genemapping animated

This example maps four genes from a small JSON dataset onto an animated SVG visualization. Each gene is represented by a colored rectangle whose width corresponds to its start and stop coordinates, with orientation indicated by color (purple for forward, teal for reverse) and vertical placement. The animation uses `d3.transition` to slide each gene from off-screen into its mapped position along the x-axis, with labels appearing at the midpoint of each gene. The code leverages D3 v4’s selection, data join, and attribute tweening to choreograph the entry, while gene names and positioning are derived directly from the data fields.

simple genome map

This simple genome map visualizes gene positions along a linear chromosome, with each gene represented as a rectangle whose horizontal span corresponds to its start and stop coordinates. The visualization distinguishes gene orientation by color and vertical placement: forward-oriented genes appear in green at the top track, while reverse-oriented genes appear in red on a lower track. Built with D3 v4, the code loads data from a JSON file and binds it to SVG rectangles, computing each rectangle’s width from the difference between stop and start values. The author uses basic data joins and attribute setters without scales, keeping the mapping directly proportional to the raw numeric coordinates.

simple genome map

This example visualizes a simple linear genome map, showing four genes as colored rectangles arranged along a horizontal axis. The green and red rectangles indicate forward and reverse orientations, respectively, with each gene labeled by name. The data comes from a local `data.json` file, loaded with `d3.json`, and each gene’s position and length are derived from its start and stop values. Using D3 v4, the code appends SVG `rect` elements for the genes and `text` labels, animating them into place with `transition().duration(1000).delay()` based on each gene’s start position.

simple genome map

This example presents a simple genome map, visualizing four genes as horizontal bars positioned along a linear sequence. Each gene is rendered as a colored rectangle, with green indicating forward orientation and red indicating reverse orientation, and is labeled with its name. The code loads data from a JSON file using `d3.json` and creates SVG groups for each gene. Using `transition()`, the bars animate from a starting offset to their final positions, with delays tied to each gene's start coordinate, illustrating the relative locations of genetic features.

simple genome map

A simple genome map displays four genes as colored horizontal bars along a linear chromosome. Green bars represent forward-oriented genes, red bars represent reverse-oriented genes, with each bar’s length corresponding to its start and stop coordinates from a local `data.json` file. The visualization uses D3 v4’s data join (`d3.json`, `selectAll`, `enter`) to append SVG groups positioned via `translate` transforms. Genes are manually offset vertically by orientation, with blue strokes outlining each bar.

Gene Map

This gene map visualizes four genes as directional arrows, with forward genes in blue and reverse genes in red, scaled by their start and stop positions from a local data.json file. Each arrow’s shape encodes orientation via a seven-point polygon, and hovering highlights the polygon, label, or tick marks with colored strokes. The code uses D3 v4 to append SVG elements—specifically `d3.select`, `d3.json`, and `svg.append("polygon")`—along with custom `GeneArrow` constructors and `Point` objects to compute geometry and tooltips.

Feb 21st- text inside rectangle

This example displays four gene features as colored rectangles along a horizontal axis, with green rectangles for forward-oriented genes and red rectangles for reverse-oriented ones. Each rectangle is labeled with its gene name centered inside using SVG text elements. The visualization uses d3.json to load the data and d3.selectAll to bind it, with each gene’s start and stop positions determining the rectangle’s placement and width. The code relies on SVG rect and text elements, with transforms translating each group to its appropriate y-coordinate based on orientation.

Simple Genome Map

This genome map visualizes four genes along a linear sequence, with forward-oriented genes shown in green and reverse-oriented genes in red. The SVG rendering uses D3 v4’s `select`, `append`, and `transition` APIs to animate each gene’s position from off-screen to its mapped start coordinate over one second, with delays proportional to the gene’s start value. Gene names are overlaid using `d3.text`, and dimensions come from the `data.json` file.
