There are a couple of problems, one minor (the :colnames yes part truncates the graph so you have only two edges), and one major: the
"params" argument is not defined.

When a dot source block is passed to org-babel-execute:dot, the params
argument I get [fn:1] is:

((:comments . #1=3D"") (:shebang . #1#) (:cache . "no")= (:padline . #1#)
=C2=A0(:noweb . "no") (:tangle . "no") (:exports . &quo= t;results")
=C2=A0(:results . "file replace") (:session . "none") (= :hlines . "no")
=C2=A0(:file . "Images/foobar.png") (:result-type . value)
=C2=A0(:result-params "file" "replace") (:rowname-names= ) (:colname-names))

So I tried passing it to org-babel-execute:dot and somewhat
to my surprise it worked [fn:2] - try evaluating the following in your
*scratch* buffer (make sure there is an Images subdir under the
current directory of that buffer):

--8<---------------cut here---------------start------------->8---

(org-babel-execute:dot
=C2=A0"graph {
rankdir=3DLR;
a [label=3D\"Omar\" shape=3Dellipse style=3D\"filled\" = fillcolor=3D\"green\"]
b [label=3D\"Hindia\" shape=3Dellipse style=3D\"filled\"= ; fillcolor=3D\"orange\"]
c [label=3D\"Yuvrai\" shape=3Dellipse style=3D\"filled\"= ; fillcolor=3D\"purple\"]
a -- b;
a -- c;
b -- c;
}
"
=C2=A0'((:comments . #1=3D"") (:shebang . #1#) (:cache . &quo= t;no") (:padline . #1#)
=C2=A0(:noweb . "no") (:tangle . "no") (:exports . &quo= t;results")
=C2=A0(:results . "file replace") (:session . "none") (= :hlines . "no")
=C2=A0(:file . "Images/foobar.png") (:result-type . value)
=C2=A0(:result-params "file" "replace") (:rowname-names= ) (:colname-names)))
--8<---------------cut here---------------end--------------->8---

But I would hardly call this method less clumsy than your earlier
attempt.

Footnotes:

[fn:1]=C2=A0 I made a simple dot source block with your graph

#+BEGIN_SRC dot :file Images/foobar.png
graph {
rankdir=3DLR;
a [label=3D"Omar" shape=3Dellipse style=3D"filled" fill= color=3D"green"]
b [label=3D"Hindia" shape=3Dellipse style=3D"filled" fi= llcolor=3D"orange"]
c [label=3D"Yuvrai" shape=3Dellipse style=3D"filled" fi= llcolor=3D"purple"]
a -- b;
a -- c;
b -- c;
}
#+END_SRC

and instrumented org-babel-execute:dot under edebug - when I executed the c= ode
block, the debugger kicked in when the function got called and I could
get the "params" argument.

[fn:2] I thought the #1 and #1# constructs (which I don't understand at=
=C2=A0 =C2=A0 =C2=A0 =C2=A0all) would make it blow up.
