This plugin adds some SVG functionality to your WordPress and uses a SVG technique that’s based on an idea by Alexey Ten and used by Jens Kuerschner which was my starting point for this plugin. 
This way of including SVG images into HTML seems to be the one with the best combination of performance and compatibility at the moment. 
Upload SVG files to your WordPress and add them to your post or pages via the SVG button in your visual editor. Here you can even select to have zoom and pan (mouse drag) on your svg, useful for maps for example. You can also set image size, a fallback image and an alt text for SEO
List of Features:
<ul>
<li>Upload SVG files to your media library</li>
<li>Use SVG files via a TinyMCE bytton or by shortcode in your posts or pages</li>
<li>Option to add captions to your SVG images</li>
<li>Option to set zoom and drag on svg images (by mouse and buttons)</li>
<li>Option to set a CSS class</li>
<li>Option to define a fallback image (usually PNG) for your SVG</li>
<li>Option to add alt-information for SEO</li>
</ul>
Example: 
[svg-complete align=”aligncenter” class=”my_own_class” svg_path=”http://upload.wikimedia.org/wikipedia/commons/9/95/World_map_frigid.svg” alt_path=”www.mysite.com/images/worldmap.png” alt=”wiki world map” width=”760″ height=”400″ zoompan=”zoom_button”]Wiki Worldmap[/svg-complete]

This WordPress Plugin adds Lightbox feature to the core Gallery block with a simple toggle button. Easily enable or disable it for any gallery block by selecting ‘media file’ under the ‘link to’ dropdown. Once selected, the Lightbox toggle will appear. It also supports custom coded galleries through a filter (check FAQ).
<a href="https://github.com/tdmrhn/dLightbox.js" rel="nofollow ugc">dLightbox.js</a> is fully responsive, supporting touch, mousewheel, keyboard, and mouse drag interactions, double click or tap/touch to zoom original image, build-in thumbnails, as well as slide counters and figcaption. With no dependency on jQuery, dLightbox.js ensures optimal viewing experiences across all devices.
Although extremely lightweight at only 2.78kb gzipped for both dLightbox.js and dLightbox.css, the plugin only loads assets into the page if there is a core Gallery block or custom selectors defined via a filter.
