<p>RCSB Saguaro Web 3D is an open-source library built on the top of the <a href="https://rcsb.github.io/rcsb-saguaro">RCSB Saguaro 1D Feature Viewer</a>
and <a href="https://github.com/rcsb/rcsb-Molstar">RCSB Molstar</a> designed to display protein features at the <a href="https://www.rcsb.org">RCSB Web Site</a>. 
The package collects protein annotations from the <a href="https://1d-coordinates.rcsb.org">1D Coordinate Server</a> 
and the main <a href="https://data.rcsb.org">RCSB Data API</a> and generates Protein Feature Summaries. 
The package allows access to RCSB Saguaro and Molstar methods to add or change the displayed data. </p>

  <h4>Assembly view</h4>
</a>
<p>Class <strong><code>RcsbFv3DAssembly</code></strong> (<code>src/RcsbFv3D/RcsbFv3DAssembly.tsx</code>) builds a predefined 1D/3D view for PDB assemblies. This method is used in the RCSB PDB web portal 
to display 1D positional features of PDB models (ex: <a href="https://www.rcsb.org/3d-sequence/4HHB">4hhb</a>). Its configuration requires a single PDB Id. 
In addition, <code>additionalConfig</code> allows to configure the feature viewer as describe in rcsb-saguaro-app <a href="https://rcsb.github.io/rcsb-saguaro-app/interfaces/rcsbfvadditionalconfig.html">API</a>.
This parameter exposes the board configuration through the attribute <code>boardConfig</code> (<a href="https://rcsb.github.io/rcsb-saguaro/interfaces/rcsbfvboardconfiginterface.html">ref</a>).
The component will be mounted in the html element with id <code>elementId</code>. If there is no html element in the current document,
a new div element will be added, and the component will be displayed in full screen mode. </p>

  <h5>Sequence panel</h5>
</a>
<p>The sequence panel organizes information in different blocks where each block encodes the configuration 
(<code>blockConfig</code>) to display one or more feature viewers. Only a single block can be displayed at a time. The optional parameter <code>blockSelectorElement</code> defines a React component 
that renders the html element used to change the displayed block. The class <code>BlockSelectorManager</code> is used to select which block is 
displayed are those that are hidden. For example, <code>blockSelectorManager.setActiveBlock(&quot;myBlock&quot;)</code> will display the feature viewers defined in the block 
with <code>blockId</code> <code>&quot;myBlock&quot;</code> (see <code>FeatureBlockInterface</code>) and hide the others. Additionally, <code>blockChangeCallback</code> defines a function that will be executed 
when the displayed block changes.</p>

<p><code>plugin: SaguaroPluginPublicInterface</code> exposes the interface to interact with the Molstar plugin
and change model representations (<a href="https://rcsb.github.io/rcsb-saguaro-3d/interfaces/saguaropluginpublicinterface.html">ref</a>). 
It provides multiple methods such as hide, display or select to modify how structural data is displayed. The parameter <code>pfv: RcsbFv</code> 
allows to access the feature viewer API (<a href="https://rcsb.github.io/rcsb-saguaro/classes/rcsbfv.html">ref</a>). It exposes methods to modify 
selections, change board configuration, zoom or adding new tracks.</p>
