This visualization displays four genes as horizontal rectangles positioned along a genomic axis, with start and stop coordinates from a JSON dataset. Forward-oriented genes appear in green on one row, while reverse-oriented genes appear in red on a parallel row. The code loads data via d3.json, then creates SVG rectangles using d3.selectAll and .data().enter().append, with x and width attributes derived directly from each gene’s start and stop values, and fill color determined by orientation.

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.

genemapping

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.

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.

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.

fresh block

This visualization presents a simple genome browser, displaying four genes as colored rectangles positioned along a horizontal chromosome. Each gene’s sequence and a descriptive function label appear near its corresponding block, with forward-direction genes in green on the top row and reverse-direction genes in red below. Using d3.v4, the SVG elements animate in sequence with staggered transitions, applying `transition.delay` and `transition.duration` to sequentially reveal each rectangle and text. The data is hardcoded in the script, and the layout derives from each gene’s start position and sequence length.

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.

Random Gene

Four gene rectangles animate horizontally onto a genomic ruler, with forward genes in green and reverse genes in red, each labeled with a letter. The SVG uses d3 transitions with staggered delays to move each gene from off-screen to its start position. Tick marks at 100, 500, and 1000-unit intervals are drawn as black rects, while the gene positions come from a hardcoded JavaScript array. The visualization relies on d3.v4 selection methods and the transition API.
