This animated visualization renders a DNA helix from a user-supplied text sequence, showing two intertwined strands that rotate over time. Each nucleotide is represented as a colored circle, with colors mapped via `d3.interpolateRainbow` based on the unique characters in the string, while connecting lines between complementary bases emphasize the helical structure. The code uses D3.js v5 with SVG elements, updating positions and scales through a `setInterval` loop that regenerates data and applies logarithmic z-depth scaling to simulate three-dimensional perspective. The animation highlights the sequence’s layout by encoding torsional rotation and opacity changes.

3D DNA HELIX Interactive

This interactive visualization depicts a stylized 3D DNA double helix, with two intertwined strands of colored nucleotide pairs (circles connected by lines) that continuously rotate and animate as the central axis twists. Mouse movement changes the helix’s torsion, altering the rotation speed and curve magnitude. The visualization is built with D3.js (version 3.5.5) and the underscore.js library, rendering via SVG. The code generates two sine/cosine-based strands, maps their 3D coordinates using linear scales for x, y, and depth (z), and updates the scene every 25 milliseconds using `setInterval` and D3’s selection/data-binding API, applying color fills from a predefined palette.

DNA sequence

This visualization animates a synthetic DNA double helix, where each colored node represents a letter from a string of fake genes and pulses along a twisting, sinusoidal path over time. It shows the helix rotating continuously, with lines connecting complementary strands and opacity varying based on depth to suggest a 3D structure rendered in SVG. The code fires a `setInterval` to regenerate and update data every 25 milliseconds, using d3’s `scaleLinear`, `extent`, `range`, and `interpolateRainbow` for color mapping. React manages the component, with fragments wrapping the DNA sequence inside the app’s root element.

Fork of DNA Animation

This animation depicts a stylized, two-stranded DNA helix constructed from a sequence of circles connected by smooth, colored paths. The parallel strands oscillate horizontally, and the connecting rungs are rendered as thick line segments, creating a simplified molecular representation. The visualization is built with D3 version 7, using its `line` generator and the `.join()` operation to efficiently update SVG circles, paths, and lines at 60 frames per second via `setInterval`. Two independently timed sine-wave functions drive the positional data for each strand.

Genome Browser

This genome browser uses D3 v4 to display four genes, each with a name, DNA sequence, direction, and function. Green forward-oriented genes animate from the left, while red reverse-oriented genes animate from the right, with sequences and function labels moving alongside. A static ruler with tick marks at 1000-base intervals sits beneath them. The visualization uses animated SVG rectangles and text elements with `transition().duration(1500)` and staggered delays to illustrate gene positions along the genome.

genome browser

This visualization presents a linear genome browser for a synthetic DNA sequence, displaying four annotated genes along a horizontal genomic axis. It shows the relative positions, lengths, and orientations (forward in green, reverse in red) of each gene, with staggered vertical offsets for readability. The visualization animates the appearance of gene blocks and labels using D3 transitions, and it renders tick marks at 1000, 500, and 100 base-pair intervals to indicate scale. The code uses D3’s selection and transition methods (e.g., `.transition().delay().duration()`) to sequentially reveal the genome, starting with the ruler, then the gene rectangles, and finally the text labels. Gene data comes from a JSON file, and the scale is fixed at one pixel per ten base pairs, with the SVG width set to one-tenth of the genome length.

Gene coding

This visualization maps six gene annotations along a linear DNA ruler. Blocks, colored green or red according to their coding direction, animate into place at their start positions, with numbered labels fading in after all blocks. The D3 v4 script builds the SVG with block append/transition methods, while the ruler itself is composed of nested black rectangles at 100, 500, and 1000-unit scales generated from a simple loop. Data is embedded directly in the code.

Multiple Sequence Aligment

This visualization displays the results of a multiple DNA sequence alignment, showing 17 sequences as a grid of colored cells where each color represents one of four nucleotide bases (A, G, C, T) and gaps appear in white. It uses D3.js v3 to render the alignment as an SVG heatmap-like matrix, with each sequence labeled on the left and a legend showing the base-to-color mapping. The dataset comes from ClustalW2 alignment results, and interactive tooltips appear on hover, displaying the row, column, and base for any selected cell. The implementation binds data to SVG rectangles and uses D3’s enter/exit selections to create the grid.

genome browser

This genome browser visualizes a 7,800-base-pair genetic sequence with an animated ruler track, using SVG rendered by D3.js. It displays tick marks at three scales—thousand-base, five-hundred-base, and hundred-base intervals—which are generated from a static array of positions. The code employs D3 data joins and `transition().duration()` to animate each tick group’s translation, creating a cascading effect where coarser marks appear before finer ones. The example’s data comes from a hardcoded `genes.json.txt` array of gene objects, though the current render focuses solely on the ruler rather than the gene annotations.
