A d3 chart for generating gene cluster comparison figures
clustermap.js is an interactive, reusable d3 chart designed to visualise homology between multiple gene clusters.
The clustermap chart expects data in the following format:
{
"clusters": [
{
"uid": <str: Unique ID>,
"name": <str: Cluster name>,
"loci": [
{
"uid": <str: Unique ID>,
"name": <str: Locus name>,
"start": <int: Locus start position>,
"end": <int: Locus end position>,
"genes": [
{
"uid": <str: Unique ID>,
"name": <str: Gene name>,
"start": <int: Gene start position>,
"end": <int: Gene end position>,
"strand": <int: Gene strand (0 or 1)>,
}
]}
]}
],
"links": [
{
"query": {
"uid": <str: Unique ID of query gene>,
"name": <str: Name of query gene>
},
"target": {
"uid": <str: Unique ID of target gene>,
"name": <str: Name of target gene>
},
"identity": <float: Percent identity query-target alignment>
}
],
"groups": [
{
"uid": <str: Unique ID of group>,
"label": <str: Group label>,
"genes": [<str: Gene UID>],
"colour": <str: Colour code for gene fill>,
"hidden": <bool: Hide group in the plot>
}
]
}
- Import d3 v6
- Import clustermap.js
- Style container div element to take up entire viewport
- Create and configure clustermap.js ClusterMap function
- Bind data to container div, call ClusterMap
