Views aggregation, sum of node count in _each row_
A no-custom-code solution could be something like this (not the most performant way though but you could perhaps do something with views caching). 

Explanation:
Create one view for the total count that with the use of aggregration and a content type filter returns the total number of nodes (the Total column)
In another Taxonomy Terms view you attach the total count view by adding a Global: View field that is provided by the Views Field View module   

Steps
 - Create a content type e.g. "Colornode"
 - Create a taxonomy vocabulary called "Colors"
 - Add three terms Blue,Green and Red
 - Add a term reference field and select Colors as the vocabulary
 - Install and enable the Views Field View  module

Then import these two views in this order:

$view = new view();
$view-&gt;name = 'nodecounts';
$view-&gt;description = '';
$view-&gt;tag = 'default';
$view-&gt;base_table = 'node';
$view-&gt;human_name = 'Node counts';
$view-&gt;core = 7;
$view-&gt;api_version = '3.0';
$view-&gt;disabled = FALSE; /* Edit this to true to make a default view disabled initially */

/* Display: Master */
$handler = $view-&gt;new_display('default', 'Master', 'default');
$handler-&gt;display-&gt;display_options['title'] = 'Node counts';
$handler-&gt;display-&gt;display_options['use_more_always'] = FALSE;
$handler-&gt;display-&gt;display_options['group_by'] = TRUE;
$handler-&gt;display-&gt;display_options['access']['type'] = 'perm';
$handler-&gt;display-&gt;display_options['cache']['type'] = 'none';
$handler-&gt;display-&gt;display_options['query']['type'] = 'views_query';
$handler-&gt;display-&gt;display_options['query']['options']['query_comment'] = FALSE;
$handler-&gt;display-&gt;display_options['exposed_form']['type'] = 'basic';
$handler-&gt;display-&gt;display_options['pager']['type'] = 'none';
$handler-&gt;display-&gt;display_options['style_plugin'] = 'default';
$handler-&gt;display-&gt;display_options['style_options']['default_row_class'] = FALSE;
$handler-&gt;display-&gt;display_options['style_options']['row_class_special'] = FALSE;
$handler-&gt;display-&gt;display_options['row_plugin'] = 'fields';
$handler-&gt;display-&gt;display_options['row_options']['inline'] = array(
  'type_1' =&gt; 'type_1',
  'type' =&gt; 'type',
);
$handler-&gt;display-&gt;display_options['row_options']['separator'] = ': ';
/* Field: Content: Type */
$handler-&gt;display-&gt;display_options['fields']['type_1']['id'] = 'type_1';
$handler-&gt;display-&gt;display_options['fields']['type_1']['table'] = 'node';
$handler-&gt;display-&gt;display_options['fields']['type_1']['field'] = 'type';
$handler-&gt;display-&gt;display_options['fields']['type_1']['label'] = '';
$handler-&gt;display-&gt;display_options['fields']['type_1']['exclude'] = TRUE;
$handler-&gt;display-&gt;display_options['fields']['type_1']['element_label_colon'] = FALSE;
$handler-&gt;display-&gt;display_options['fields']['type_1']['element_default_classes'] = FALSE;
/* Field: COUNT(Content: Type) */
$handler-&gt;display-&gt;display_options['fields']['type']['id'] = 'type';
$handler-&gt;display-&gt;display_options['fields']['type']['table'] = 'node';
$handler-&gt;display-&gt;display_options['fields']['type']['field'] = 'type';
$handler-&gt;display-&gt;display_options['fields']['type']['group_type'] = 'count';
$handler-&gt;display-&gt;display_options['fields']['type']['label'] = '';
$handler-&gt;display-&gt;display_options['fields']['type']['element_label_colon'] = FALSE;
$handler-&gt;display-&gt;display_options['fields']['type']['element_default_classes'] = FALSE;
$handler-&gt;display-&gt;display_options['fields']['type']['separator'] = '';
/* Filter criterion: Content: Type */
$handler-&gt;display-&gt;display_options['filters']['type']['id'] = 'type';
$handler-&gt;display-&gt;display_options['filters']['type']['table'] = 'node';
$handler-&gt;display-&gt;display_options['filters']['type']['field'] = 'type';
$handler-&gt;display-&gt;display_options['filters']['type']['value'] = array(
  'colornode' =&gt; 'colornode',
);

/* Display: Block */
$handler = $view-&gt;new_display('block', 'Block', 'block');


And the second one:
