Make a graphical representation of BLASTn alignments

Homology Visualization (HomologyViz) uses GenBank files (.gb) to align the sequences and plot the genes. HomologyViz uses the information from the CDS features section to plot the genes. To customize the colors for plotting genes, you can add a Color tag in the CDS features with a color in hexadecimal. For example, add the tag /Color="#00ff00" to show a green gene. Or, you can edit the colors interactively in the plot.

HomologyViz is an easy-to-use option for people with little coding knowledge. The program uses Dash for an interactive and web-friendly experience. HomologyViz is a flexible app that allows you to export your graph in different formats and sizes for publication quality.

Notes

I am developing HomologyViz in my free time, so if you find a bug, it may take me some time to fix it. However, I will fix the problems as soon as possible. Also, if you have any suggestions, let me know, and I will try to implement them.
